chiwi has been a little grumpy these past 2 days. like she has mood swings! one minute she's all loving next minute she nips me and walks away to her bed and lays down. i'm not sure what her problem is. maybe it's because she is teething? maybe it's been hot here lately (84 yesterday and about the same today)? she's 5 1/2 months now, is it puberty? i've never dealt with a young female dog before so i don't know the attitudes.... any suggestions?
