My boxer is 10 months old, almost 11 mo. We also have a chocolate lab. THe boxer has been doing well with house training, there have been mistakes of peeing here and there, but no serious problems. About a month ago when it was really storming my husband took him out to pee with the other dog and there was a loud crack of lightening and he was teriffied. Another time when it was raining and thundering we came home and took him out of his crate, and he was stiff, and shaking... very afraid. Now, when it rains he doesn't want to go out. In fact yesterday he peed in his crate (after we got home for a car ride from the beach)... it was raining out though. We did yell at him and tell him he's bad. Later on in the day when we tried to let both dogs out he didn't want to and peed in the house. At night before we went to bed he peed in the house again and was too scared to go out.
Now, this morning it took a lot to coax him out but if I petted him he was SO happy and wagging and came out with me. He didn't want to get off the deck to pee though. I reallly don't know what is going on. He's not fixed yet, we may breed him in December and then get him fixed after that. Could that be it, or is he just super scared now of rain... and just scared to go to the lawn and pee too?
You have a very smart dog there. I would use a leash, and use food as a tempter, and make him go out, especially if it isn't raining. Many dogs are terrified of thunder and lightning; so that's not a surprise. If I were you I would try and make a place that is at least covered over, like a car port; so he doesn't have to get into the rain. I would physically carry him out there, and if that didn't work, I'd soak up a place in the house where he has peed with a pee pad, and confine him to an x pen, or a part of the house that he can't damage the flooring. Overall though, I would persist as hard as you can with the leash and treats, and maybe a little shove from behind from another person. I would not force him out in thunder and lightning, I would just use the X-pen.
You mentioned breeding him, and the fact that you wondered if his being intact had anything to do with his fright. He's not old enough to breed, and no I don't believe being intact is a reason for being afraid of thunder and lightning.
It sounds like a mild fear has blown into something beyond that. If one of my dogs was afraid enough to go outside that it made him pee inside? Um he'd be spending a LOT of time outside, rain or shine. We have a dog that doesn't like to go outside when it rains, but we make him go outside anyway, and don't let him back in until he does his business.
When he is afraid, you can't reassure him, as tempting as it is. In a dog, reassuring them when they are afraid can actually make a bad situation worse, because they begin to think, "Oh no if she's reassuring me, it really must be even worse than I thought!" Any time a dog is exposed to something it's afraid of, instead of reassuring the dog you actually want to ignore the stimuli, and treat it as though it's absolutely normal and/or ignore it. If you give him extra attention you're feeding his fear.
If your yard is fenced in and safe for him to go out in, if you feel that it's time for him to go out, make him go out, rain or shine. As soon as he potties, let him back in.
Regarding breeding him, eesh he'll be too young to breed in december. Not to mention boxers are prone to a variety of health problems. Have his hips OFAed, his eyes CERFed and make sure he's had his heart checked out by a cardiologist. The OFA hips won't be certified untilt he dog is 2+ years old.
Never trust a tall dwarf... he's lying about something.
