I have a 5yr old male Rottie who lives with a 4yr old female Pompom (both unnurtered) I know! I know! before you say anything the pom was never nurtered due to medical condishion vet would not do it to much of a risk. Back to problem the male dog gets left in the house while we are at work and he keeps peeing on the same 3 spots. I cant put him outside right now it is to hot 110+ outside and i feel the kennel is to small to be in for 7+ hours. We clean the spots with pet stuff but he keeps doing it. Do you think if we get him nurtered he will stop or reduce the peeing. I cant stand it and now we need new carpet. Please Please Help.
PS male dog not nurtered because he came with husband and he felt he was not being a man by chopping his nuts (somthing we fight about all the time)
as for it stopping him from marking it may and it may not, this late in the game, so to speak, he is used to doing it so he may never stop. My male used to mark as soon as he was in another dogs house, or a male dog came into his house, he was neutered at 2 and has finally stopped, but it took a couple of years. Another option is to get him belly bands http://www.jjdiapers.ca/content/Belly%20bands/bellybands.html see if having to make his manly dog wear them around the house will entice him to neuter the dog,
I have never delt with this before, the cat peed on hubbys pillow once and of her went to the vet 3 days later, LOL.
It doesn't sound to me like he's marking, especially if he doesn't do it when you're home, so I don't think neutering is going to help, although it can't hurt and having it done is in his best interests.
He may be experiencing separation anxiety. Google it and determine whether he exhibits any of the other behaviors common to SA dogs.
