I have a 4month old JRT bitch called Dotty. She gets fed 3 times a day but she's really greedy. No sooner have I put the bowl down she's in and the food is practically gone she's like a hoover, Dotty doesn't seem to chew her food just swallows. I feed her on dry puppy food mixed with gravy so the bits aren't big. Do you have any ideas on how I can slow her down whilst eating??
