I have a 1yr 1/2 old male american bulldog. He was given to us around june of this year. He was house broken. I also have a 3yr old jackrussell that recently had puppies and stays in our kennel. she had stayed in the house with him for a few weeks because it was to hot out side for her to have the puppies. when she was in the house my male bulldog started pooping in the house. i just thought it was due to the fact that we have never been able to house train my jack russell. now that the jack russell is back outside my male is still pooping in the house and getting into the trash. he has also got on my kitchen counter to get meat that was thawing out. we play with him and love on him daily, i do not understand why he has changed his good behavior.
