Were they stitched?

I really don't have any good advice for you, except to make a trip to the vet if the bleeding continues (at least that's what I'd do) ~ I'm sure someone here will be able to help you more.

When Josie was "fixed" . . . it was almost as if they closed her incision under the skin and then pulled skin overtop of the incision and stitched that together too . . . it was really strange looking, but she pulled several of hers out and I was so worried that she'd pull the whole thing open . . . but she never did.

Good luck & keep us posted!
