A couple of years ago Lacey started drinking water like crazy and had to pee a lot and even had a couple accidents in the house. After spending a weeks pay on tests she got better and it was suspected to be hormonal.(she is fixed) The test results came back right after she started getting better. The vet had suspected this and we tried to wait awhile before we had tests done but started getting worried.
Best we could figure she was upset because we had leashed Mandy(because she started having spells due to her heart condition) and it upset Lacey.
Have there been any changes that could have upset Buddy? I don't even know if males can have hormonal problems, but I guess they could. Just a thought. It made me think of what Lacey went through. Good luck at the vets tomorrow and please keep us posted.
