I have been eyeing Bonnie's little round belly too. I am afraid I have been giving her too many "trick" treats.
I don't really give her any people food. She eats NV raw. But I was also putting out 10-12 pieces of kibble for her to nibble on. I stopped that a couple of weeks ago. Her treats are being broken into smaller pieces,
She is due a vet check up. I know her vet is going to say something about her "round-ness"
