2. How do I housetrain two 12 week old old puppies (a boy sheltie and a girl duchshund) when I don't have a set schedule? My boyfriend and I work and have classes at different times each day, so it's not possible to say "Ok, they'll eat at 9 am and at 4 pm everyday." We've had a sheltie for about 5 weeks and the dockshund for about 1 1/2 and the housetraing isn't going too well.
3. Why does the 1 year old female shih tzu hump the sheltie?
