I have 5 dogs who rule my house. Two toy poodles Asher age 9 and Abby age 10. They are my "big" dogs and are fairly calm and well behaved. Abby is not real sure why all these little dogs keep kissing on her but as long as they stay out of her bed and don't jump on her roughly she is okay with it. Asher acts like a 12 week old puppy since we got the yorkies for him to play with. Then we have our yorkies Isabella age 1, Sasha 10 months, and last but not least Piper our biewer who is about 5 months. For us they seem to like to have a regular structured routine on what time they go to bed, cuddling on the couch in the evening, their playtime outside and even naptime as the 3 little ones all seem to fall asleep at the same time everyday. I have to admit we do tend to structure our daily activities around their needs but as they 3 younger ones are getting older it is getting easier. I love ALL of the quirky personalities!
