We have previously had some aggression issues with Caesar but we've been working on it and he's been great for months now. Last night was differant. He started to bark at the front window for no reason. The blinds were closed and Emma (German Shepherd X) who is our resident guard dog wasn't concerned. He went into our bedroom and didn't want to leave. The dogs are not allowed in there unless we are there. So I tried to use my body (legs) to move him towards the door. He barked and growled at me the whole time but he eventually left the room. Then I was in the kitchen getting my lunch together for today. I opened the cupboard with the tupperware and he tried to get inside which is typical for him. Usually I'll go to close the cupboard door and when it touches his bum he moves out of the way. Last night was differant. He freaked out, growling and barking almost like a nasty temper tantrum. So Emma came in and barked at him which made it worse. I eventually got them both to be quiet but I realised that my foot and pant leg were wet. There was a few spots of pee on the floor, not like a full pee, but like he lost control and peed a little. We did recently change his food and (this might sound nutty) there is full moon tonight. I didn't yell or anything like that, I always try to stay calm (we watch a lot of Dog Whisperer). It breaks my heart to think that he was so angry that he actually lost control of his bladder. I'm at a loss to think of why he reacted so strongly.
