I Have an 1.5 yr old Male unneutered High drive high energy Border collie lab mix, which we raised on marker training. Hes turned into a great dog- with literally one bad habit.
He urinates in innapropraite times and places. First of all, he will on occasion (like once a month or less) pee in his crate. Its not that he drank too much and had to go, or that he is spending too much time in the crate. It doesnt happen often enough for us to sit and wait for him to do it so we can work on it.
Also, when we are out working him around distractions in the park or the pet store, he gets so excited that he will just pee where he sits or as he heels. It would be really nice to not have to worry about your dog peeing when your in someones house or ON you while your out (yes thats happened too, acutally...lifted his leg on both me and my husband, at different times)
Does anyone have any experiences specifically with this?
He definitely does not have a UTI, already made sure.
As far as the peeing because of excitment, I understand that just teaching him to calm down maybe our best bet there but if there is something else we can I would love to know!

Excitement peeing is much different from lifting his leg on the pack leaders!

So IMO these are two very different questions, and the first one is probably much simpler to answer and fix. The second one, if he is actually deliberately lifting a leg on you, is going to need all-around adjustments in the way you live with this dog.

Please describe the circumstances surrounding an instance of the dog peeing on you.

well he is an extremely careless pee-er
He doesnt have terrible good aim, and is too lazy to aim or balance for the whole performance. He usually gets himself in the leg, and even saw him get himself in the head once. when he lifted his leg on me he was sniffing around and when he turned before lifting his leg, ended up pointed at me and then just...went! Same deal when he did it on my husband. I've seen a dog deliberately mark someone and it really seems more like he just doesnt care.
Its revolting to watch him do his business because he has such bad habits, I guess im used to dogs who were really concientious but he will pee while hes walking because he cant be bothered to stop and do it all at once (the same with pooping actually, just like a horse).
So what do you think?

I have a nasty dog as well. I love the big oaf, but he has many of the same habits you describe... Pees on his front legs/chest, brushes the urine that he just sprayed in a bush, no regard for piles or puddles, and as a youngster did try marking on a human once or twice....

The marking thing was super corrected and has not happened as an adult, but I can't do much about the other nasty stuff.... I just keep him as clean as I possibly can. Baby wipes and waterless shampoo are staples with this dog.

I do guide him to the areas where I want him to relieve himself to keep the mess to a minimum, but there is no way I am going to guide him to the point of showing him how to hold his leg....

haha I hear you....we just look away and try not to gag...he gets an undercarriage wash pretty often
