My 18 month whippet was spayed 3 weeks ago, she made a very quick physical and apparently emotional recovery after her laparoscopic procedure, but has been possessed by pixies for that last 2 weeks... its like having the super naughty 6 month puppy again which was a phase we were VERY glad to leave behind. She wants to play ALL the time, she won't let our other whippet rest... constantly barking at him to play and wrestle with him, and wanting to play silly bitey face. She is stealing, rummaging, chasing the cats... all things that had stopped ! Ummmm..... help ????
