Our Charlie was also sick when we first got him so the potty training was delayed abit. We were crate training him and LOTS of accidents! I was frustrated and bought a portable play area. He didn't mind being in it but always picked a corner to pee and poo! So after almost 2 weeks I took it away and went back to crate training. I have been back for almost 2 weeks and he hasn't had one accident in his crate! I can't figure it out...LOL I also have been teaching him to paw the bell on our door to go outside. The last 4 days he has been doing this and everytime he has done his business outside. He is picking up on things quickly now that he is feeling better...there is hope
