My 2 year old female basset (Scarlet) has apparently forgotten how to be potty trained. All of a suden she is scared to go outside. I have to shove her outside or carry her and then she still won't go potty outside. She used to be the best, she would jump at the door to go outside and she learned this right away. Haven't had a problem until the last couple weeks. She did just come out of heat, I don't know if that has anything to do with it. This was her 3rd heat and never noticed this problem before. I tried making going outside fun with a treat and stuff but it hasn't worked. What could she be so scared of all of a sudden? My other girl is having a similar problem but it isn't near as bad. Any thoughts?
