Fenbendazole

25

If you have a dog or cat that comes into the clinic and has chronic enteropathy, what is the first therapy you should try?
You have already ruled out parasites.

Try a food trail
In cats - 7 day elimination trial
In dogs - 14 day elimination trial

26

If a food trial does not work to treat chronic enteropathy, what should your next therapy be?

Try antibiotics - Metronidazole is the most common
Others that could be used are Tylosin and Oxytetracycline

27

What food additive should you use to try and treat for colitis?

Fermentable fiber (psyllium)
