Thank you for the welcome, Wendy!
I travel for work every other month and when I return, she is so excited and happy but I think it overwhelms her that I was gone and then returned. She starts throwing up her food and will have horribly bloody diarrhea. The last three times, we took her to vets who stopped her up, gave her the rice/chicken diet, tested for parvo, giardia, cancer, liver issues, allergies, parasites and found nothing. One doc put her on anti-depressants which helped.. But eventually, it will go away.. While we're treating her, it's traumatic for all involved. She feels horrible for being unable to control herself and we feel bad b/c we know that my leaving is upsetting her. I'd say about $1500 worth of tests and not having an answer the fourth time around is discouraging. I've been to two vets, too..
Anyway, I'm hoping someone may have been through this and might have a solution in how to help. I appreciate the ear!
