My 11 week puppy has been with us for almost three weeks now. We started crate training right away and he was so great at going in, whining for maybe a minute then going to sleep. However the last two nights whenever we put him in he barks and whines his head off for over thirty mins. He still has his favorite toy in there, a bed, so nothing has changed. We haven’t made it a bad place- he still gets treats in there. The only thing that changed was he had some medication that made his stomach upset and he had diarrhea for a day. During which we let him mainly stay in his play pen and put him in the crate to sleep once he fell asleep and took him out frequently since he had to dedicate more often that day. Did doing this accidentally set a new habit? Anyone else have a dog regress in crate training?
