we bought a new jack russell puppy yesterday, aged 6 weeks.
since we brought it home she's been quite sleepy (understandable). She didn't eat yesterday and has only eaten this morning and not since. She also doesn't seam to be drinking either.
Do you think we should worry about her? She was given a clean bill of health by a vet just prior to us getting her. The seller has suggested trying to get her to drink but we're unsure how?

Thanks for your help
