Izzy too! 10-15 seconds and she will finish 1 cup of kibble. She does not chew on it... she just inhales and then looks at me like I didnt give her enough. She doesnt throw up after eating so I never worried about slowing her down. The only thing I did because she was all over me when I was scooping her food is to make her sit and wait for a command to eat. I put food bowl down, make her do the hi five... sometimes 3 times if I noticed her super anxious! then I let her have it! That seemed to make her calm down a bit but she still a fast eater.
But ...hey... I am not complaining. I can feed Izzy/walk and complete potty break in less than 10 minutes and I live on the third floor of an apartment complex! She is my ninja
