Laika is slightly "touched". Really, she's a nutter. Every once in awhile, about once or twice a day, she gets a bit crazy and just decides to bite us. It's relatively gentle biting usually in the form of ankle nibbles or hand chews and generally inspired by play or good petting. It's hilarious, but still a bit worrying. I've never known a dog that did this before. She's like a cat, that lashes out when they are most enjoying a pat. Crazy dingo.
