Hi, I'm new to this site & a new puppy owner. Our 13 week old Chihuahua/Terrier mix can hold it all night long, 10pm to 6-7am, but during the day while I'm at work, he doesn't. I come home every 4-5 hours, sometimes sooner, and he's already gone pee & poop in his crate. Originally we started off having him stay in the kitchen w/a baby gate, but he had a lot of room & was going to the bathroom daily, that we made it smaller. As it got smaller, he continued to go to the bathroom, this time on his blanket, not caring. We purchased a small crate, but if he sits/lays he still has about half of the back empty w/room. Every day between 7am-noon when I get there, he has gone pee & poop inside. Originally we were leaving the same items (shirts, blanket, towel) we do @ night, but he would still go. He's down to one small, thin kitchen towel. Sure enough today I got home, he had went. After I get home from work he will hold it, and won't always go right away, not until about 10 when he goes to bed. He goes outside every nite before bed, sleeps in a crate w/the shirts, blanket, towel & holds it. My Fiance stayed home the first 5 days we had him to train him, but obviously it didn't work. We take him out often so we never have accidents inside, just the crate. Please help! Do I need a smaller crate, what are we doing wrong?
