New Problem - 'pee pee' in living room - HELP

We've had Cashemere now for almost two years. We used to live in an apartment and he never did 'pee pee' inside at all - we always walked him outside with no problem. When we moved to our new house, the previous owners had cats and dogs who I'm pretty sure went to the bathroom in the living room carpet and before we removed the old carpet, Cashmere started to pee on the carpet even though we walked him still. After we removed the carpet and put new tiles Cashmere is still doing this......What do I do???

it's possible thee old pet urine penetrated through to whatever was underneath the carpets (the padding and maybe the wood). Have you tried neutralizing? I use Nature's Miracle whenever our 9 month old pup has an accident.

Has he been doing it since you moved in consistently? It could be him marking territory or just adjusting to the new place.

Have you checked into a possible medical reason? some animals pee because the have an infection

Just an update - Cash is doing much better now and hasn't done 'peepee' in almost two months....we walk him on a regular schedule every day and I think removing the carpet worked also. Thanks to all who replied...
