This isn't entirely relevant to this forum, but none of them were and it's kind of an odd question.
How long can a dogs "belly button" be? I apologize for not having a picture at this time, I can try if it's necessary. The reason I ask is that I have a neutered male rescue (beagle-dachshund mix at best guess) that I noticed has a long scar where his belly button should be. My other dogs is just a small spot, and he is a much larger dog, where-as Moe is half his size and his is really long, almost like an incision. As he is a rescue, I have no clue what his medical history is, and it was just a little concerning that perhaps he has had previous medical issues or surgery that I don't know of and could be a future concern? It wasn't noticed prior to his last visit, but I will certainly bring it up at his next for a professional opinion. The scar is about an inch long and has a clean cut incision look to it almost.
Just thought I would ask, I haven't seen too many dog "belly buttons", but collectively I am sure you all have enough to know if this is normal.
