For the past day, Chloe has been refusing to go outside. I say outside and she comes to the door but as soon as I open the door she lies down. She eventually comes out but then it is a huge struggle to get her go down the hall. She used to love going outside. The only thing I can think of that changed was that she met up with another puppy yesterday and he was jumping at her. Chloe had the tail between the legs. I quickly got her out of the situation. Do you think this could have caused her setback?
