I have an MVD dog and I have a lot of experience with Liver Issues. Even though her BAT wasn't into Liver Shunt territory (100+), her number of 47 was still higher than normal. It could have been the antib's, but she most likely has MVD. The crystals in the urine suggest that as well. So with that being said, if she has MVD, YES the toxins CAN and DO cause some aggression.
Spaying her should also help, but you need to know if she has Liver Issues, so you and the Vet can take the proper precautions during the spay, and possible Liver Biopsy (since she will be under already).
What diet and supplements are you givinh to her now
