If you love this dog in all other ways and you don't think you'll find another just as good without hip dysplasia, I'd still find an orthopedic vet to evaluate. But I know that in some cases these types of joint problems can worsen with age. So if I were in your shoes, I'd either keep looking or get the dog checked out by my own choice of vets and it would be a reputable orthopedic specialist.
Best wishes for a good outcome.
