Can diet really affect my pets health?

Your pet’s diet has a big impact on their health and wellbeing. The wrong diet could lead to your pet developing health issues such as obesity, diabetes, pancreatitis, allergies or dental problems — so getting it right is crucial!

DOGS

It’s important to feed your dog a complete, balanced, high-quality diet. High-quality commercial dog food will contain all the right nutrients and vitamins, and in the right amounts. The best way to recognise a decent quality diet is to take a look at the list of ingredients. The first item should be an animal protein e.g. chicken or pork. If the item is, for example, chicken ‘derivative’ or ‘meal’ this tends to imply a lower-quality diet. Avoid any diets where the kibble is a range of bright colours which means there are likely to be added colourants and additives. These are added to make the food look more appealing to you, whilst your dog doesn’t care what colour his food is!
It’s also key to feed a diet appropriate to life stage and age of your pet. As you can probably imagine, a Great Dane puppy has a completely different calorific and growth requirement compared to say, an elderly Chihuahua. You should feed a good quality puppy or junior food up to the age of about 1 year (sometimes longer for large breed dogs – usually to about 15-18 months), then gradually switch to an adult diet, then to a senior food from the age of 8.
If you have a large breed dog, then you should feed your dog a diet specially formulated for large breeds. This is because joint problems tend to be more common in larger dogs, so these diets contain additional joint supplements to support bone and joint health. Small breed dogs can be more prone to dental disease so generally diets suited to smaller breed dogs have a smaller kibble size and contain supplements to reduce tartar build-up (which can lead to dental disease).
Once your dog has been spayed or castrated, it’s a good idea to feed a neutered diet. These diets are calorie restricted to help prevent post neutering weight gain. It’s vital to maintain a healthy weight and body condition score (BCS) – extra weight puts your pet at health risks including diabetes, arthritis and heart problems. If your pet is a little on the porky side and is already carrying a few extra pounds, then special prescription weight loss diets are available.

CATS

Cats are obligate carnivores, so it’s important that they are dependent on their diet containing meat to thrive and survive. In a similar way to dogs, they should be fed a life stage-specific diet based on their age.
Most adult cats are lactose intolerant (they lack the main enzyme required to digest lactose in milk) so it’s best to not feed your cat milk.
Prescription diets are available for certain health concerns including – kidney disease, liver disease, diabetes, arthritis, overactive thyroid (cat), skin problems, urinary problems and cystitis, obesity and many more.

RABBITS

The bulk of a rabbit’s diet should be hay (fibre) or dark green leafy vegetables – a minimum of 80%. This should ideally mimic what a rabbit would eat in the wild. A small amount of dry concentrate food can be offered, usually about 1 tablespoon per rabbit.
It’s important to feed a complete pellet concentrate, as muesli mixes promote selective feeding and can lead to dental problems. Diet is particularly important for rabbits to wear down their teeth, which continuously grow. Feeding an unsuitable diet can lead to overgrown teeth, weight problems, fly strike and lack of grooming.

What should I feed my dog?

There are a couple of age old mantras such as “you are what you eat” and “food is medicine”, both used to deliver the message that our nutrition and our diet, has a major impact on our health. It’s the same story for our pets — so what should I feed my dog we hear you say?

HOW OLD IS YOUR DOG?

Human infants and toddlers have different dietary needs to the likes of teenagers and OAPS as they are at different stages of their lives — it’s the same for dogs. A young puppy needs lots of energy, protein and calcium for growth of muscle, tissue and bone. An older dog, perhaps starting to slow down, needs rather fewer calories.

WHAT BREED IS YOUR DOG?

The difference in size and shape of the jaw may mean that different sizes or shapes of kibble are more easier to chew — this is particularly true of smaller short-nosed dogs, who can really struggle with some sizes of kibbles.

Endurance dog breeds such as Collies are “always on the go” whereas smaller and toy breeds (such as Yorkshire Terriers and Chihuahuas) tend to live a more sedentary lifestyle — which can dramatically impact on their calorie requirements.

HOW BIG IS YOUR DOG?

The adult body size of your dog can affect their growth rate, and their dietary needs, when they are younger. But alongside this, several scientific studies have found evidence which suggests that food moves relatively more quickly through a smaller sized dog, than through a large sized dog, meaning more frequent meals may be needed, or a diet with a different fibre content.

WHAT KIND OF LIFESTYLE DOES YOUR DOG HAVE?

Top performing human athletes require very different diets from your normal office worker — in the dog world a good equivalent example would be the Labrador Retriever. A working Labrador will have different needs to a couch cuddling Lab. Remember, too, that where they live is important! A dog who lives in a kennel probably needs more calories than one who sleeps indoors by the fire, for example.

DOES YOUR DOG HAVE ANY DIETARY SENSITIVITIES?

Some dogs can suffer from allergies and intolerances to certain components of a diet, causing itchy skin or upset tummies for example. Understanding your dogs specific needs, things to avoid, and even methods by which diets are made, all helps to select the right diet.

DOES YOUR DOG HAVE ANY MEDICAL NEEDS?

Some diets are “prescription diets” which have scientific proof demonstrating that they help to control or prevent health issues such as bladder stones, kidney problems or liver issues. Other diets are formulated to include nutrients which may help manage things like arthritis.

COMPLETE DIET OR COMPLEMENTARY DIET?

These two terms sound very similar but what you may not know is that there is a very important difference. The term “complete diet” is a legally protected term in the EU, and using it means that by law, that diet must contain the required energy and nutrients (vitamins, minerals etc.) in the correct proportions. A complementary diet doesn’t have to meet these requirements.

Feeding a complete diet is essential to provide everything your animal needs. When a diet provides too much of something, it can lead to toxicities. For example, dogs fed too much Vitamin D can ultimately suffer from kidney failure. This is one reason it’s important not to feed too much offal in a raw diet.

ARE THERE ANY SPECIAL REQUIREMENTS FOR SAFE HANDLING AND STORAGE OF THE DIET?

Some diets (especially raw ones) may require you to keep in the fridge or freezer, and may have a specific time period for consumption. Feeding these diets may also mean accepting an increased risk of encountering some bacteria which can be harmful to humans such as E.coli, Campylobacter and Salmonella .

The best way to minimise this risk is to change your usual hygiene practices when preparing a pets meal and when cleaning up faeces, to minimise the exposure of you or your family to the bacteria.

Every dog is an individual with their own specific needs and no-one knows those needs better than you and your vet. If you’re feeling a little overwhelmed by choice, or just looking for the best diet for your pet, book an appointment with a member of our team. we can discuss a unique individual nutritional assessment for your pet and then recommend a refined range of diet options available to you.

Common Toxins Dangerous To Your Pet

Certain types of food and household items can be unknowingly toxic to your pet — read our list of the most common toxins dangerous to your pet below.

If you think your pet has ingested one of the following please contact your vet immediately. If you are concerned your pet has eaten something poisonous not listed please use our online poisons guide for advice.

FOOD AND PLANT TOXINS

Chocolate – causes heart rhythm abnormalities and nervous system signs (eg excitement, tremors, seizures). Just 15g of dark chocolate can be toxic to a 10kg dog.
Onions – cause anaemia by destroying red blood cells.
Garlic – believed to have a similar effect to onions.
Macadamia nuts – in dogs, cause weakness, inability to stand, vomiting, depression.
Avocado – fatal in birds and rabbits. Avocados contain a substance called persin which is highly toxic.
Grapes and raisins – can cause kidney failure in dogs.
Raw or undercooked meat – diarrhoea and/or vomiting (due to Salmonella or e.coli bacteria).
Fungal toxins (mouldy food) – diarrhoea, tremors, seizures.
Bread dough – disorientation, depression, weakness, coma.
Acorns – diarrhoea, kidney failure.
Lilies – have been shown to cause kidney failure in cats.
Brunsfelsia – (“yesterday-today-and-tomorrow”) – diarrhoea, seizures.
Oleander, rhododendron, azalea, crocus, foxglove, hyacinth bulbs – Heart problems.

HOUSEHOLD TOXINS

Antifreeze – causes kidney failure, cats and rabbits need to ingest only very small amounts to show symptoms.
Tea Tree Oil – depression, weakness, incoordination, muscle tremors.
Pyrethrins, Permethrins – usually found in supermarket / pet shop flea products, toxic (especially to cats) if ingested; causes salivation, tremors, and seizures.
Paracetamol (panadol) – toxic to the liver and interferes with oxygen transport, can be very quickly fatal in cats.
Ibuprofen (nurofen) – depending on amount eaten, can cause gastrointestinal ulcers, kidney failure, and/or seizures.
Aspirin – can cause gastrointestinal ulcers.
Bleach and other cleaning products – many of these chemicals are highly acidic or alkaline, and can cause tongue and mouth ulcers when licked by dogs or cats.
Rat poison– causes blood clotting problems, seen most commonly as internal bleeding, or blood in stools or urine, or vomiting blood.

What is haemangiosarcoma?

Haemangiosarcoma is an aggressive type of cancer which arises from cells that line blood vessels. In this blog we will focus on haemangiosarcoma in dogs as, although it can occur in other species such as cats, this is very rare.

Where do dogs get these tumours?

These tumours have a point of origin (primary tumour), but very often metastasise (spread) to other organs causing tumours elsewhere (secondary tumours).

As blood vessels are almost everywhere in the body, they can occur in many places. Primary tumours most commonly appear on the spleen, but they are also frequently seen in the heart, liver, skin and subcutaneous tissue.

Haemangiosarcoma is the most common type of tumour affecting the heart, accounting for around 69% of heart tumours. It is also the most common malignant tumour to affect the spleen. Much of this blog will relate to haemangiosarcoma of the spleen (splenic), as this form often creates the most discussion, concern, and questions.

Why did my dog get this?

We do not know why certain individual dogs are affected, although we know that, in skin, haemangiosarcoma is linked to sun exposure.

Certain breeds are predisposed. While German shepherds and golden retrievers are prone to the visceral (organ related) forms, whippets, dalmatians and bull terrier breeds are prone to the skin forms.

What signs might my dog have?

The signs depend on where the tumour is.

Haemangiosarcomas of the skin usually appear as a small red or bluish-black lump. They can also occur in deeper subcutaneous tissues, often sitting under normal looking skin.

Haemangiosarcomas located in the liver or spleen often grow rapidly, forming cavities containing blood, often only revealing signs when they rupture causing bleeding. This sudden blood loss can lead to weakness or collapse, and is the most common way dogs with this condition present to vets for the first time. Collapse can also be caused by disturbances in the rhythm of the heart, which can happen in primary heart tumours, but also those in the spleen. Occasionally these tumours are picked up early due to swelling of the abdomen or vague signs of illness. Because the tumour and blood loss can cause clotting issues, bleeding from the nose, or another area, may occur.

How will my pet be diagnosed?

The appearance of skin or subcutaneous masses may lead to our vets advising a biopsy, or removal of the mass. Samples sent to a lab can confirm a diagnosis.

With the visceral (organ) forms, diagnosis can be challenging. Dogs we suspect of having a heart, splenic or liver haemangiosarcoma often arrive as an emergency, with severe internal bleeding. Suspicion may be increased by finding a mass via ultrasound scan of the heart or abdominal organs. However benign tumours, malignant tumours (such as haemangiosarcoma), or non-tumours can look similar on an ultrasound scan, but would all carry very different outlooks. If there is evidence of more than one organ being affected, metastasis is suspected, increasing the likelihood of haemangiosarcoma. There is currently no concrete way of confirming the mass type until tissue samples are examined after surgery. A recent study showed that 63-70% of dogs that present to the vets with abdominal bleeding (not caused by trauma) have haemangiosarcomas.

Occasionally a mass is picked up during an ultrasound scan for a different problem. This gives more time for decision making and surgical planning.

How are these tumours treated?

The skin and subcutaneous tumours can be surgically removed with margins of normal skin. As 30-60% of these tumours will metastasise, it is important to remove them. However they may have already spread at the time of diagnosis. Tumours extending into deeper tissues may benefit from chemotherapy (anti-cancer drugs), or radiotherapy, in addition to surgery.

Treatment of splenic haemangiosarcoma involves surgery to remove the spleen, with an additional option of chemotherapy. These drugs are usually well tolerated but can sometimes have side effects like lethargy, anorexia, vomiting, diarrhoea, and fever. Mild to moderately low white blood counts occur in up to half of dog cases but usually do not require treatment.

Because splenic masses often present as an emergency, decisions regarding surgery often have to be made before a clear diagnosis, and thus prognosis, can be given. Removing the spleen is a major operation and can be risky, with some dogs not surviving the procedure. If the dog is subsequently diagnosed with haemangiosarcoma then the outlook is very gloomy.

Factors such as age, other illnesses and signs of spread must be taken into consideration with decision making. All situations are individual, but for some dogs euthanasia may have to be considered as a treatment option, especially if the outlook is poor.

What is the prognosis?

Skin and subcutaneous tumours, once removed, can be examined to give better information on the severity or ‘stage’ of the tumour. Stage I tumours just affect the skin and are associated with an average survival rate of 2 years, whereas stage II and III tumours that either involve the subcutaneous tissues or muscle have a worse prognosis if treated with surgery alone. Chemotherapy or radiation therapy may improve this.

Sadly haemangiosarcoma of the spleen tends to carry a poor outlook. They are often malignant, and most individuals survive less than 3 ½ months with surgery alone, with very few living beyond a year. If there is no evidence of spread, or tumour rupture, and chemotherapy is used, there is an average life expectancy of around 8 months. If the tumour has ruptured, it can be expected to reduce to an average of 6 months.

Although haemangiosarcomas can be found in many places, the splenic form often creates most difficulties in decision making. Our team will be there to support you, talk you through all of the options, and help you through any difficult decisions.

Reducing Roaming

One of the most common causes of death for dogs is, sadly, traffic accidents. However, entire male dogs are at a significantly higher risk than others. The reason is biological – but the risk can be dramatically reduced by neutering!

Why do we recommend neutering?

There are a number of advantages to having a dog neutered – eliminating the risk of testicular cancer, reducing the risks of prostate disease, some types of anal cancer, and unwanted behaviour such as humping and, crucially, “roaming”.

What is roaming?

When a female dog is in season, she releases pheromones that can be smelt by dogs for miles around. Male dogs are driven by instinct to seek out the bitch to mate. As a result, even well trained dogs will sometimes run away when lured by the attractive scent. This behaviour is sometimes called “roaming”, but in our modern built-up environments, this usually means crossing busy roads and potentially coming to grief.

What is the procedure?

Neutering of a male dog is a very straightforward procedure, involving the removal of both testicles under a general anaesthetic. Your dog will come in to us in the morning, have the procedure, wake up, and then almost always go home the same day. In fact, in most cases the procedure only takes 15 minutes or so! Without testicles, the dog no longer produces significant amounts of testosterone, and this instinctive behaviour is dramatically reduced.
