Hi everyone. I was wondering if anyone else has every experienced this problem. My puppy, Phoebe, had a correct tail set when I first got her at 12 weeks of age. She held her tail over her back end, resting the tip on her back. Now, however, at age 5 and 1/2 months old, her tail is held either curved up like a saber or straight out. I cannot for the life of me figure out why this has happened. She has not suffered any injury or anything like that. If anyone has any input, it would be appreciated. Thanks.
