5-Year-Old Jack Russell Beagle mix poops in the house
Five years ago, my sister rescued two Jack Russell Beagle mix sisters (Daisy and Ozzie) for family pets. She said that both seemed to be completely potty trained until they reached the age of two, then both started pooping in her house - while urinating outside when she would take them out. Unfortunately, the poop in the house problem got so bad that she put both in an outside dog run with no house privileges. Because of this, another sister and I have taken the dogs into our homes. In their new environments - for over 6 months - the pooping in the house problem still exists. I have two other dogs and they all get along fine with each other. That said, when Ozzie goes outside with my other dogs, she will sniff both their urine and poop and will procede to urinate. I praise her for that, but despite the few times she has pooped outside and gotten praise, she still poops in the house. Her poop is firm and the vet says she's in great health. There is no specific situation or time of day when she defecates in the house. In fact, all the dogs can simply be walking from one room to another and she stops and poops. We've corrected her with a sharp "No" when she does it, but it hasn't done any good. When she sees me cleaning up her mess, she does the submissive roll onto her back as if she knows she's goofed again. Are there any tips that anyone can offer?
Any help will be greatly appreciated.
