My dog eats her food in under 30 seconds. She inhales it like she's never seen food before! She's an appropriate weight and even a pound or so over according to her vet. I bought a slow feeder bowl, but she won't use it and walks away. Is this when I think if she's hungry enough she'll eat? Or should I try and replace the bowl and get a slow feeder that's a bit easier? Part of it, I think, is her collar tag hits the bowl and I know she doesn't like that, but even when I took that off, she lost interest.
