She's 8.5 years old. I looked through the papers I got from the breeder I adopted her from when she was 4.5 years old and she has one of the genes that causes DCM. I'll let the woman know if she is diagnosed with it. The ethical thing for her to do is to inform the owners of Bella's offspring so they can monitor their dogs more closely.
At this point, she's already lived longer than 3 of my past Dobies, 2 of which had sudden death from DCM.
She isn't doing bad. She still gives a good 10 minute blast of running when we first get to the fields but then tends to just walk along with me with a few bouts of exploring.
I think she's having arrhythmia episodes that scare her. She'll be resting and then just bolt up and run off. When I put my hand on her chest I can feel her heart beating really fast. She did it again last night. I'll make an appointment for the vet to listen to her heart and see if he hears a murmur. That's typically the first sign.
Brodhi's mom has access to a Holter monitor from her former breeder so I can put it on her and send the data to a cardiologist to read it then get the report back to my vet so he'll prescribe the cocktail: Pimobendan, benazepril and furosemide.
