Hello. I have two Jack Russells, the older one a Jack Russell/Chihuahua mix, and I love them both. The older one, Milo, named after the dog in The Mask because his face is completely brown as if he's wearing a mask, gave me lots and lots and lots of problems for years but somehow we weathered all that, and now he's the most loyal, trustworthy, housebroken dog you could ask for. He'd had it all backwards at first, thinking that houses were the place you went in, and he would refuse to go outside. (After all, humans go in houses, cats go in houses, why not him? Why was he the only one required to do his business outside?) It took 5 years to get through to him, but he finally, finally learned and is 100% trustworthy now. My second dog, he's pure Jack Russell, and he seems to think, well, I don't know what he thinks, except that he absolutely has to mark everything. He is kind of housebroken but he goes in the house whenever he is so inclined, and he marks every day, including the water dish, the food dish, and anything that manages to fall to the floor, even a Christmas card. What is he thinking? He tries to act like he doesn't need me and that punishments don't matter to him, Mr. Tough Guy, all independent and contrary. I try to do the things that worked for my other dog, although there was no single breakthrough. Any advice? I don't want to wait another 4 years for this guy! Help!
