My puppy is 8 weeks old, but I got her at 7 weeks. I would give yours a little sugar in his water or give it some nutri cal or White Kayro syrup before you leave it alone, My baby had a seizure because I thought she was just tired but her sugar level was low from not eating much . Even if you are not having the problem I would do it to be safe untill she is a little older. It happened so fast, if I had not checked on her she may have died. I don't want to scare you, it's just that is very young to be away from Mom, I found out the hard way. Congratulations on your new fur baby
