Answer

Thanks for the question XXXXXXXXXXXXX.

The most likely cause of a dog dragging it's behind on the floor and bouncing would be impacted anal glands this would not be related in any way to the spaying. The anal glands are normal structures in all dogs both male and female and impaction is a very minor condition which you vet will relieve in about ten seconds.

However other conditions which can cause irritation in this area are worm infestations and eczema of the outer anal area.

While you can learn to relieve blocked anal glands on your own it is not everyone's cup of tea so the best advice I can give you is to have your vet check your dog over, confirm the diagnosis, and sort things out. The chances are this is a very minor condition indeed.
