Once our new house is built, my husband and I want to get a playmate for Tika. We want a large dog, because she seems to play with them better, and we want one who will swim with us, because Tika will not be caught near a lake - and, it would give me some peace of mind knowing Tika has a 'protector' with her in the back yard when we may not be outside. Tika runs in and out of her doggy door all day and night. While the yard is fenced in, and she usually stays with us, I do still worry about coyotes, mountain lions, bobcats, etc… It is not unusual for any of those three to walk around our house at night.
Any suggestions on what dog may be a good choice to just be a protective presence for her? I am okay with getting a "mut" as well!
