What can i do for Male Poodle peeing in house and bed?

I have a 3yr old poodle with a peeing problem. He did good with the doggie door the first 6mths he lived with me. I got him when he was 6ths old. I also have a female schoodle. I got him fixed when he was a little over a year because he started the marking of territory in the house. We have lived in our house now for a little of 1 yr and he continues to mark and the new thing for a about 6mths is pee on the bed. What can i do? PS my female is not fixed could that have anything to do with it?

Please bring a fresh urine sample to your vet to make sure that he doesn't have a urinary tract infection and have a bladder X-Ray to make sure that he doesn't have a stone in his bladder.

If he doesn't have a urinary tract infection or bladder stones than please try a DAP collar or infuser.  DAP collars give a dog a feeling of well being and can sometimes aid inappropriate urination.  DAP infusers are available at pet stores, some vet offices and online.

If all else fails he may need professional training.  Ask your vet for the names of reliable one on one dog trainers in your area.
