My dog has nearly casterated himself the vet has stitched him up but is is still bleeding and now and again clots are passed, He can we and Poo with no problems. This happened on Monday 3rd Sept how long will it be for the bleeding tom stop

We can't answer that! There are too many factors starting with what kind of cut 'nearly castrated' means (did it happen going through a fence?). Ask the vet. I know it's the weekend, but leave a message and say what the question is. Is your dog wearing a cone?

The bleeding should have stopped.

You need to contact your vet so they can look at the incision. If its not healing right, they need to know.
