Re: Normal Bump???
I remember laughing with my boyfriend at Mischa because she was a 'conehead'. She's at 12 weeks now and it definitely is not as pronounced as Lia's.
I would do what vizslandobes suggest and speak to your breeder first. It could also just be a hematoma, which is a bruise with swelling that will eventually go away. Puppies are always bumping into stuff, especially vizsla puppies with their gangly legs and growth spurts.
