Yes, it's true my new rescue just went almost 17 hours without peeing or pooing. Background before question: Shelter rescue, ~2y/o M Brussels Griffon/Border Terrier mix, have had him almost 8 weeks. We just finished our first manners class and he seems to be doing well. He has been having some potty accidents in the house (pee and poo). My trainer suggested was to start right from the begining taking him out every hour and if he doesn't go, he gets popped into the crate. We are on day four. The second morning this happened and he went 16 hours but I got him out in time. This time, we were going every 5 minutes for the last hour. I popped him back in the crate and he peed. He has also pooped in the crate in the past. When we go out, we go to one spot in our yard. He is leashed and not tied out. We are out for 3 minutes and right back in. I can guarantee a poo if we go to his favorite spot way down the road or if we go somewhere in the car and get out he'll go immediately. I am not a new dog owner and have never had this problem with a dog and I've had several rescues over the years. I've even trained a dog to sneeze on command. Potty training should not be this difficult, should it? I'd welcome any suggestions. Thanks!
