I am again asking for help with my Morkie. He had settle with everyone's help so we had him neuter at 7 months nearly. After he recovered from the operation he became very anxious, barks at slightest noise, nipping, jumping on and nipping our older dog and finally the odd pee on our bed!!! He is cage trained, house trained and had more toys than my children had we asked our vet but she just says he is naughty and shouldn't be allowed upstairs. He has always been clean upstairs and slept on our bed with our yorkie, it wouldn't be fair to leave him on his own downstairs now. The only thing I can think of that might have started this off was that a black cat had sneaked up stairs whilst I had taken the dogs for their late walk and had say on our bed. I washed the bedding and duvet but as soon as I put it back on he peed on it so I through the duvet away. He had peed once just a week before that happened on my sons bed. He didn't do this before he was neutered but our vet just thinks it is bad behaviour is there anyone with any ideas?
