Good morning. A year ago I came on worried about Arabella's heart. Still worried, but all in all her heart has done well on the medication. She hasn't had any collapses. At least not from her heart. I was out of town because my mother was hospitalized and left my husband in charge of the dogs. I get a phone call from my husband who is very upset. He is asking me why I never warned him about seizures. I assume she collapsed from her heart and tried to calm him down. After a few more phone calls and she is still having issues, but it is not the typical heart collapse. When I got home after a couple of days, I watch my girl's back end fall out from under her over and over. I immediately take her to the vet. After running several tests, it is determined she most likely has a brain tumor. My world was crushed. We have her on seizure medicine on top of all her heart meds. Thankfully they are working as she hasn't had a seizure since that first weekend 2 1/2 months ago. I do see an occasional leg tremor and some difference in the way she moves, but for now she is happy and still enjoying her life. She turns 13 in December and right now I am optimistically planning on celebrating it with her.
