LOL... sorry... but I can see doing that myself with my lab.
I say keep trying, eventually she should get used to it once she realizes that this is how the food will come from now on. But I would not hand feed her.
Yeah, Barley looked at me funny and whined a few times but it didn't take long for him to dive right in. Keep trying! I can see Koko's wheels turning..she's thinking "what? I have to work for my food?" LOL! Maybe put some treats in it later tonight for practice.
She'll get the hang of it. Say no to those big brown eyes... when she's hungry enough she'll deal.
I bought one for Mya when whe was a pup because she hoovered her food. It never bothered her a bit, just slowed her down a little LOL! Your pup will get used to it as everyone says.
I got Bruno the Slow Feed bowl at Pet Supply Plus (similar to Break Fast Bowl). It was so funny to see him finish his meal last. But now I think he's learning his way around it and he finishes in the same time it takes the others. It still doesn't keep him from swallowing without chewing.
