Dawn, I just saw this thread. I am so glad you got some food into Jude. I do understand this--it is so hard, devastating.
Tipper's problems with Peroxicam started with loss of interest in food. If this continues, or if you see any vomiting, PLEASE get blood work done. This was the sign that my dog's kidney failure was starting. Make sure Jude is drinking well. My dogs were on the Purina EN (dry and wet) and it was prescribed for liver and digestive issues. I strongly suggest getting some of the Merrick canned food. It looks so much like human food and smells wonderful. Grammy's Pot Pie was a favorite of my dog with liver cancer. Link to Merrick foods:

I tried this trick with Mac (the one with liver cancer). Put equal parts peanut butter and water in a bowl. Heat in microwave and stir together--it will make a syrup-like mixture. Put the dry food in a food processor and grind to a powder. Mix the food powder and peanut butter mix together and shape into bite-size pieces. You will need to adjust the ratio so the food will form the small balls/patties. It looks like a no-bake cookie. Mac ate these. The peanut butter has protein and lots of calories. Just don't give too much peanut butter if he is sensitive to oils/fats.
Know Jude is in my thoughts. This is a very difficult road. We did need to syringe-feed our dog with TCC. I will not recommend this, but know it is an option. Also consider Nutri-Stat or Nutri-Cal for extra nourishment.

Tipper's kidneys went bad after only 2 weeks on the medication. Please get the blood work to check BUN and Creatinine if the inappetite continues. Sending my best and please keep us updated--lots of us care about this special fluffy big boy.
