I'm having severe difficulties training my dog. I just adopted him from the local SPCA who told me he was paper trained so I went and bought some puppy mats. Aiden is an 8 month old terrier/poodle mix. I am single so while I go to work he is stuck in a crate all day. I take him outside to relieve himself in the morning before I go to work and immediately upon my return home. he has only had one accident in his crate since I've brought him home. after I take him outside it's hit or miss on whether or not he'll go (he'll usually pee but hardly ever poops) that is until he gets back inside. about 10-20 minutes after I bring him back inside he's ready to go... on my carpet, he never chooses the tile in the kitchen. I feel bad leaving him crated except for bathroom breaks but at this point I have no clue what else to do. I give him treats and praise him whenever he goes outside, any advise would be GREAT!!!!!!
