Canine Respiratory Illness

We have had many questions about the mystery of respiratory illness affecting dogs in certain states. As of right now, we have not seen many of these cases at Riverside, and none of them were serious.

Symptoms of this upper respiratory Illness may include:

Coughing that doesn’t get better on its own after a week or so


Nasal or eye discharge


Trouble breathing, especially with noticeable abdominal effort

Bluish or purple gums, due to lack of oxygen

Kind Words from Clients

I only had great experiences with Riverside, I take both my dogs there. My senior dog has several health issues due to his age, and they have been more than helpful and attentive to him. All the vets and assistants are super caring. I only take my fur kids there. The ladies from the front desk are friendly and they go above and beyond to help.

Dr. Lagasse is amazing. I have a stubborn cat who can become very angry when at the vet, making it hard for most to manage. Instead of sedating her (others have only worked on her if sedated) Dr. Lagasse was able to do a visit AND lab work! Impressed, amazed, and very thankful.
