need help/advice

hi all i have a 9 month old staffy and the last month he has been peeing on his kennel (outside walls) now as i said this only just started to happen and it is frustrating because it happens at night or early mornings so i can't catch him in the act, he is pretty good with toilet training so i don't know what has changed
Any advice to stop this behavior, or any reasons why this would happen

thanks rich

I guess he doesn't sleep in the kennel ?? But it seems he's trying to mark it as his own. Could another animal be around it when he's indoors ?

Thats the thing he does sleep in the kennel and he is an outdoor dog, the kennel is under a verandah and no other animals go near it

Still he's marking for some reason, it may just be getting to be a teen - hormones setting in. Does he having other good peeing places in the garden ?

sounds like either marking property of regression on the toilet training front. both can happen at this age, my girl was toilet trained from an early age and then at 8 months decided she was going to start crapping all over the house! had to go back to basics with her for about two weeks.

What are you cleaning the mess up with?

thanks for the replies
- yes he does have other paces he pees on i've got a bin on the grass he mainly uses
- i wipe the mess up clean with soapy water and then spray with vinegar and water mixture thats what i was tol by the people i brought hm from

but yeh looks like I have to go back to basics with him for a while

Try cleaning the area with biological washing powder, this will remove the scent rather than just masking it. Going back to basics again will help.
