As recommended by the vet, I put Buddy (11 years old) on Hills JD rx to help his mobility issues. This, as a result of my telling the vet about his loose footing and rear leg weakness. He's been on it for about a month now, if I remember correctly.
This food is corn-based and has about 17% protein. The food he was on previously was TOTW Salmon which is about 25% protein.
The issue is that he seems to be foraging in the earth for more...something, I don't know what...protein?. He'll do this "hunt for food in the ground" typically right before his regular feeding time, however...its not limited to this time.
Anyway, I thought maybe his body is craving more protein. So, I started topping his RX food with canned TOTW; and yesterday I added a cup of TOTW kibble. I think that serving was too much. It was 2 cups of the RX, 1 cup of the TOTW kibble and a heap of the TOTW can. He only ate about half of it and said..."I full Ma."
Also, he seems to be losing more weight...I can see his ribs. I know we want to keep him thin and the vet said getting him to 104 would be good. He was 114 at last weigh in. That was another reason I thought we could afford more food at mealtimes.
Thoughts? Suggestions? Ideas as to why he is foraging?
