We are just getting Bonnie back to normal after her spay nearly 6 weeks ago

Although it was not house training, it was ALL other training. Its as though the spay sent her back to her puppy days. She wouldn't even sit for us; jumped and bounced at everyone and everything. We have had to go back to basics with all her training. Was like starting over again and I can only think that it is the hormones that sent her a bit crazy.
As it is toileting, it might be to do with her internal discomfort, as others have said so best get Mouse checked out. As long as your vet rules out any infections, I'd say just start again with toilet training as if she's a pup......blooming frustrating I know but its as if they forget everything. Best of luck and hope she improves quickly xxx
