My parents have a 12 wk old puppy named Edison. They have had him since he was 5 weeks. They take him out to potty every hour and he goes, but when he comes inside, he'll go again (usually pee) within minutes. WHAT are they doing wrong?? What should we change? My mom is out of town for the next several days, so the pottying will be left to me & my dad.Id like to have the pup trained by the time my mom gets back.
