My wife bought a beagle pup several months ago as a 50th birthday present to herself. Beagles are stubborn little guys, sweet and loving but will knock you off a roof to get to a potato chip. This is the third beagle we have owned and the fifth in my family, so we're used to the breed's idiosyncrasies. The problem is this particular dog refuses to be housebroken. In all honesty, he's not the brightest dog I have owned but I have never had an issue with housebreaking before so I am no expert on the subject. All the dogs I've owned in the past had just 'gotten it' after praising and rewarding them for doing their business outside several times. This dog just doesn't get it. He'll relieve himself outside then come back in the house for a repeat performance. He knows he is wrong as he avoids us after doing the deed, but that never stops him. We walk him constantly and let him loose in the yard several times a day so he's definitely not lacking for outside space and smells, yet he is never good more than 50% of the time. Any recommendations? Thanks much!
