I am new to the Chi breed, but now have 2 and my husband has 2. We live apart during the week and are all together Fri night thru Monday morning. We each just had one and they sleep in their crates. Now with the 2 new additions (all of this has happened in a 2month period!) not sure if we should get 2 more crates or let them pair up at night. Any suggestions? Oh, I'm new to the group too, so thank in advance for your help!!
