We have two 5 yr old small male Yorkies, Sawyer 3 lbs., Benny 5 lbs., and one 13 yr old Border Beagle mix, Sparky approx. 20-25- lbs. Sparky is cage trained and the two yorkies sleep with mom & dad. The little ones do not go outside, they wear diapers for peeing and unfortunately poop in the house, for which they have a routine.
