So sorry to hear about your loss Wolfpack.
Delta is hanging in there, but honestly we don't know for how long. She has given up on dry food completely, and is eating about 2 cans of wet food a day. But even then, she appears to be losing weight. She still goes for two walks a day with me (1 mile and then a mile or less depending on how she is feeling and how cold it is), and still tries to get fries and pizza crusts from me, so she hasn't given up yet.
We go to the vet tomorrow for another check up. Hoping against hope that she has at least maintained weight.
The worst part is that I have to go on a business trip out of the country next week. I just pray she makes it through that.
