Welcome! My name isXXXXX am a 2003 graduate from UC Davis, and currently a Medical Director of a veterinary hospital.

I am sorry to hear about this concern for Nanook.

Well, one of the most common symptoms or complications with just about ANY of the non-steroidal anti-inflammatories is vomiting or diarrhea.

I would absolutely have no reason to assume that this is a sign of liver distress.

Of course, if the stools were to get worse on the medication, you'll have to stop and switch to a different anti-inflammatory.

Since you mentioned severe arthritis, here is a bunch of info about the most popular medications vets use:

A few common medications prescribed by vets (not all options,but many of the most common choices): NSAIDS,
Pain Control

Currently, one of my favorite joint support supplements on the market is Dasuquin or Cosequin. Here is some more information about it. Many veterinarians and clients have observed that after a few months on a quality joint support product, they can often reduce the dose of the non-steroidal anti-inflammatory medications there pets may already be taking. A supplement can take several weeks to observe benefit, so it is important additional anti-inflammatory or pain medications are used in the meantime.

Also, an incredible clinically tested food to help with joint problems is J/D.
J/D Diet
Another supplement to review would be Adequan injections for joint health. These injections are also quite popular and have helped many pets with arthritic disease.

I hope that information has been helpful.

two quick questions..


what are some signs of liver distress?


what causes yellowish stools and is that in itself a concern??


i will watch for vomiting or diarreha as a side effect of the rimadyl ,thanks.

Specifically, we would really need to see some changes on a blood profile, to show elevating liver enzymes.

With more severe liver complications you may observe icterus (jaundice), or yellowing of the skin.

Yellowish stool is different than yellowing of the skin.

Stool can be all sorts of colors depending on how fast the food transits through the gut (if too fast, too slow, if on medications).

Some vets suggest also starting some liver support supplements if there are some mild increases in liver enzymes and needing to continue anti-inflammatory drugs.

Definitely, look up a supplement called "Denamarin". Can be very helpful.

Hope that additional information helps. Definitely, reply to me if there is any other way I may assist you. I hope my responses have been satisfactory?
