Senior Pets

Looking after
your senior pet

When is a pet classified as being senior or mature?

Dogs and cats are considered to be mature adults once they turn 7 years old. Large breed dogs age more quickly and are considered mature at 5-6 years of age.

What are some of the signs of ageing that a pet owner should look out for?

A pet owner may notice changes to the pet’s appearance such as some grey hairs appearing. Pets may also develop hearing loss and reduced vision.

Even if a mature pet does not outwardly appear old, certain changes are progressively taking place. These include changes in their organ systems such as their immune system, digestive system and certain behavioural changes. Behavioural changes include things like changes in their interactions with the family, changes in thinking and becoming confused about where the door is or where their bed is. It can be alterations in their sleeping patterns and toileting accidents when they were previously well toilet-trained. And with advancing age there is also an increased risk of many age-related complications and disorders. Click here to read more about signs that are not normal age related changes.

What care should I be providing to my ageing pet?

All pets should be kept up to date with all preventative health care, regardless of age. This includes vaccinations, worming and flea control (amongst other things like ticks and heartworm depending on location). Having a daily dental care routine is vital to protect against dental disease. All pets should receive regular veterinary health checks and should be fed age appropriate nutrition. Hill’s Science Diet portfolio provides science-led nutrition for healthy older dogs and cats of every size and a variety of needs.

Older pets should be groomed regularly to keep their coat healthy. This is particularly relevant to older cats with mobility issues who may struggle to groom. Regular grooming can help to stop painful and unattractive matts from forming.

Why should I feed a senior/mature adult food to my pet?

Older animals often have decreased nutrient digestion, which means they cannot absorb the nutrients from their food as well as younger animals. It is therefore important to feed a food made with easy-to-digest ingredients for healthy digestion.

Older pets can also be prone to weight gain as they are not burning as many calories exercising, so it is important to feed foods that are specially formulated to support their energy and activity levels. Feeding a food containing high quality protein to support lean muscles will also help a mature pet maintain a healthy body condition.

Senior foods should also contain balanced minerals to support kidney and heart health, because excess minerals can lead to worsening of underlying disease.

Hill's Science Diet Senior Vitality range is our breakthrough formula to help improve your senior pet's everyday ability to get up & go.

When should I switch to a senior food?

Even if your pet is not showing any outward signs of ageing, they should still be transitioned to a senior food at 7 years for cats & small/medium dog breeds and 6 years for dogs > 25kg. It is important to recognise that the benefits of feeding good nutrition accrue over a long period of time, so it is important to feed your pet a food appropriate for their changing needs throughout their lifetime.

How frequently should we be taking our senior pets for a check over at the vet?

The general consensus from veterinarians is that senior pets should be checked by the vet every 6 months (or more frequently if there are health concerns). Whilst it might seem frequent, it is actually only every 4 dog or cat years.

Check-ups are an opportunity to raise any concerns you might have, as well as have the vet perform a thorough physical examination of your pet. The vet may also recommend blood and urine tests to screen for diseases. This gives you the best chance of detecting something early so that it can be treated or managed successfully.

Exceptional vet service. I have three cats and a dog and have been taking them to Yeronga Veterinary Clinic for over twelve years. I have always found the staff to be caring and professional. Their compassion and the dedication shown to each animal is of a high standard. I would recommend this clinic to anyone looking for outstanding care for their pets.

We moved into the Yeronga area over 18 years ago with our 2 border collies and were fortunate to have someone recommend the Yeronga Veterinary Surgery to us. Since then they have supported us through many wonderful moments when we added 2 wolfhounds to our family and adopted 2 kittens through their adoption service. They have also supported us in the most devastating of times losing 3 dogs over the years. Anita and her team achieve the perfect balance of being excellent vets providing the best of care for pets (and their owners) in a genuine caring and compassionate manner. We are always able to book appointments when needed and have been seen promptly when we have had emergency situations too. I would highly recommend Yeronga Veterinary Surgery.

I have been a patient of Yeronga Vet Clinic for over 20 years and wouldn’t go anywhere else. Dr Lisca and the team are second to none. Recently my 3 year old Labradoodle Daisy ruptured her cruciate ligament and underwent surgery. The professionalism and care Daisy received was top class. I would recommend Yeronga Vet Clinic to anyone looking for a great vet service for their fur baby.

We first came to Yeronga Veterinary Surgery nearly 4 years ago, carrying our tiny black Labrador puppy Delilah in, hoping to find some guidance and caring attention, and just a little bit of shared dog-madness. Well, we were in luck, and we have never looked back. The team at Yeronga Vet Surgery have been nothing short of exceptional at every step of our journey with them. From the basics of preventative care to important surgeries (and the odd mini-emergency thanks to our hungry labradors…) everyone has been both professional and welcoming, and more importantly, extremely good at their jobs! I am constantly blown away by the care and attention we receive, and the fact that our dogs cry with excitement when we pull into the street says it all. We’ve never had dogs who are so excited to visit the vet. We can’t recommend the team highly enough – they are exceptional.

Hi there puny human my name is Bastet. Here is a picture of me in all my glory to help your feeble human brain rest for a moment so I don’t pile on to much information at once. Ready? Nevermind let’s continue. Every few months my manservant deems it necessary to verify the divinity of close personal friend Zeus and myself, here is picture of us looking regal. I know you’re thinking “They are clearly perfect why would he waste their time.” and the answer is frankly he’s not very bright but means well so we indulge him. One thing we demand in return is that he takes us to the Yeronga Vet Surgery where we know we will be shown the respect and deference as befits ones such as us. So if you must interrupt the napping, playing or eating of your betters take them to Yeronga Vet Surgery.

Yeronga Vet have alway been wonderful in their professionalism and care over the years for those furrier members of the family, adding a healthy dose of genuine sympathy for those less routine difficult visits.
