So Mason is potty trained; he doesn't go in the house etc. Great. But I sware that dog holds it all day long! The thing is, he has access to the back yard. But does he use the facilities out there? No. He holds it. Why? Because he knows at some point in the evening he is going to go for a walk and need lots of ammo. My complaint is that when we come home his bladder is so full; he ends up peeing all over when we try and pet him. He's so darn excited to see us; he looses control. You can tell his bladder is full just by looking at his belly. We've tried Vitamin B, we've tried ignoring it, we've tried telling him know, we've put up with it for 3-4 months hoping it would stop but it doesn't. It doesn't improve in the slightest. It's also frustrating cause he'll sit right in it and then need washed; but he hates being washed. Ahhhh. Any suggestions?
