I recently adopted a bulldog puppy, she’s almost 14 weeks. The only problems I have are that she messes in her crate but will bark to get out how do I remedy this? her crate is big enough for her to stand up turn around and lye down. I started only giving her treats outside with lots of praise for going out. She will jump, bark or bite to let me know she wants out. I can’t break her from the biting even with playing and affection which leads me to put her in timeout for 10 minutes. She also won’t walk down steps and is very adamant about not walking on the leash! She’s already 19 pounds and gets quite heavy to carry up and down stairs. Any suggestions?
