Well, we did just recently fence in the back yard which is around 1 acre or a little bigger, which is nice, as I can let them out to run for 10-15 minutes a night..But, when my little shih tzu got run over, I missed 3 days of work..
Her puppies were 11 or 12 weeks old when this happened..
You may need to get your babies those cute little rain coats they have at walmart...LOL
