Cognitive Dysfunction

Has your pet ever done something out of the ordinary and you hear yourself thinking “he’s just getting old?” Perhaps you thought your furry family member is going senile? Well, you may be right; there is a condition of animal senility called Cognitive Dysfunction.

Cognitive dysfunction has a similar appearance to Alzheimer’s disease in humans. Owners may notice changes in their beloved pet such as changes in activity level, new patterns of interaction with their family, new sleeping patterns and excessive vocalizing.

The mechanism behind the cause of cognitive dysfunction is not known, but research suspects it is similar to humans – a build-up of sticky proteins around the cells of the brain which disrupts the transmission of signals.

If you’re worried that your pet may have cognitive dysfunction, it is important that your veterinarian rule out all serious medical conditions first. Your veterinarian may provide you with a checklist, called DISHAA, to help you identify if your pet is exhibiting signs of cognitive dysfunction.

Treatment for cognitive dysfunction includes managing your pets’ environment – providing extra bathroom breaks, a night light or a new daily routine. There are special diets to help your senior pet with cognitive dysfunction that is fortified with medium-chain triglycerides and antioxidants. Ask your vet if one of these diets might be right for your pet.

Watching your special furry family member get older can be hard, but with the help of your veterinarian, you can bring in their golden years with a smile on your face.

Our veterinarians are currently seeing all patients by appointment ONLY.  We continue to operate with a "closed waiting room" in order to keep our clients and staff safe during the pandemic. We appreciate your patience and understanding as these appointments take a little longer than normal.  

How do appointments work?
Please come to the back door for your appointment and call 416-537-3128 upon arrival. A veterinarian will speak with you over the phone and a veterinary assistant will come out to collect your pet for an examination. After examining your pet, the doctor will follow-up on the phone with their findings and recommendations. Thank you for entrusting us with the care of your pets. Please let us know in advance if they have any special needs.
Payment Methods:
We are currently accepting all payment methods. However, credit or debit cards are preferred.
How to collect food and prescription orders:
We appreciate advance notice for food and prescription refills. Please call 416-537-3128 upon arrival at the FRONT DOOR and a receptionist will be out with your order as soon as possible. For faster service, we suggest ordering pet supplies and food through our online store.  Delivery is free with purchases over $100.00.  It's easy!  Just click ONLINE STORE on our website to sign up.


Thank you for your patience and understanding and we look forward to seeing you and your furry family members again!
