My 6 week old boston terrier puppy isn't eating. We've been feeding him soft food, with a little kibble which has been working fine for about a week, and just today he started not eating and is acting a little strange. I don't know what it could be and I'm really worried about him! Please help!

It isn't a concern if a puppy doesn't eat the first few days in a new home. I am afraid this now sounds like a bigger problem. Call the vet in the morning. Tempting a dog that isn't eating with rich food is nearly always the wrong thing to do.
