I feel your guilt! Hallie too is on a diet! She loves green beans so I've been doing that per my vet! And on rainy days I run up and down the hallway with her for excercise
And on sunny days we go for long long walks. THe problem in my house is that Simon needs to gain weight and Hallie needs to lose so meal time is always an adventure
Keep us informed of the diet progress, good luck!
