Absolutely agree with all - see the vet cos if there is anything wrong, it will be caught early and so more treatable/controllable.... if nothing else, it will put your mind at rest.
Good luck with it and really hope puppy is OK.
Please keep us informed on how it goes.
Very big welcome to the forum Jane - don't be frightened to ask anything on here. There are some great folk and the forum is a collective tower of experience and advice. I have had gsds for over 30 years and still learning things on here.
