MY 7 weeks old golden retriever puppy has dark bloaches on skin on it's tummy... they don't look that bad... but I'm just an overly-concerned mommy, I guess. :) I just want to make sure that it's nothing to worry about.

You should be in for shots before long. Ask the vet then. Some times they have infections because their immune systems don't kick in right away.

I hope you just got him. I think 7 weeks is OK, but before 6 weeks they need their mother and littermates.

Yes , I just got him, I did have to wait till week 7 exactly because he couldn't be separated. I'll be sure to mention it to the vet.
