we recently adopted a puppy from an animal shelter. we have had her for about 3 1/2 weeks, she was kind of skinny when we got her and even though we feed her regularly, 3 small portions a day is what our vet said to do, she doesn't seem to be gaining any weight. last night when we gave her a bath she shed an unusual amount of hair and today her nose has been running the same way as a persons does. what can i do? please help. she is 5 1/2 months old.
