My dog is limping a bit

So no swelling and he's still playing. Is he even still limping? I mean, the good thing about being a young pup is that the healing process can be very fast and it's as if nothing happened. Their bones may not be as soft compared to when they were a new born to a couple of months old but it can still heal fast as they still in the juvenile stage of their lives.

Speaking of 400 Euros, I'd go bankrupt in a year if vet bills were that high in my country.
