Savvy {8 month Sheltie} was spayed about 3 months ago and only recently we have noticed there is a dark stitch now protruding from her underside. I have never seen this on any other spayed dog nor was it on Savvy earlier.
Please comment ...
Izzie had one left after her spay and i just left it then 6 months later pulled at it a bit and it came right out. I'd check with your vet first though.
