Just posting in case anybody can share about a similar experience. I posted a few weeks ago about Mindy developing a sudden fear of thunder at 10.5 months. We got through that experience OK for a couple weeks. In the last few weeks we’ve had bouts of diarrhea. They stop after a day with fasting and bland diet. We eliminated some fish chews we thought might be contributing to the problem. In addition to occasional diarrhea, Mindy is getting spooked hearing cars outside our condo. Mind you, we are on the third floor and the street is a good half block away. It’s the trucks in low gear or motorcycles that bother her. She hides in the bathroom or her crate and sometimes takes half the day to come out. Yesterday, she was at the groomer where she’s always done fine. She hid a lot when we came home. Then, diarrhea last night. I was up with her four times. This morning she is hiding. BUT outside she is happy and jumping around and playing. Not sure what is going on here. Two separate issues?? Anxiety? Colitis related to stress and/or food?? we had a fecal done at vet last week and it was negative. Anybody else have experience with acute onset of fear? She will be one year in 8 days.
