This is a timely discussion for me as I spent several hours today bathing and grooming all of our yorkies. We have three grown females and one grown male -- two of these have 3/4 's of a full coat, one is pregnant and one is nursing. We have our four little boy puppies -- 6 weeks old now and running everywhere, they had their first baths today.
All dogs live in our family room/kitchen with us, and sleep in crates in our bedroom at night. The puppies are kept in a playpen in our bedroom at night and in a playpen in the kitchen when I have to be away during the day. Otherwise they run in the kitchen with an x-pen fence to keep them off the family room carpet.
There is going to be some overlap between the litter we have now and our next litter (due in 2 weeks). We know we have at least 4 puppies in the next litter (sonogram). Fortunately after the first few days, newborns are pretty easy to care for (assuming no problems).
I have reached my limit.
