Thanks for replying Chachi
How long is TOO long? I'm still not sure when I should start to be concerned. He is also getting neutered tomorrow and they say no food/drink after midnight - will this be okay???! I free-feed him and sometimes he has eaten it all when I get home from work and sometimes, very little. That's when I get concerned. He never seems to be anything other than a healthy energetic puppy though. I have tried canned food and he doesn't seem to eat that any better either. I will try chicken - thanks
