Dog ate chocolate?

Boxer fainted.

Species: Dog
Breed: Boxer
Age: 1-2 years
My 1 1/2 year old boxer fainted or collapsed yesterday evening as he was walking to the door to go outside. He just woke up from nap since he played all day at the daycare. (He goes to 1-2 a week.) As we were about to head outside and go down the stairs he lost control of his whole body and almost fell down. He pretty much collapsed and then lay down. I actually had to catch him otherwise he would have fallen down our stairs. It happens in a matter of seconds and then he was fine. I am contacting the vet today but was not sure what the cause may be and how concerned I should be?


Online vet, Dr. Marie

Dr. Marie replied:

It sounds like you may want to talk to your vet about a condition called boxer cardiomyopathy. Some boxers can be born with a heart issue that can cause fainting or even sudden death.

They will likely recommend an ultrasound of the heart.

I hope everything is ok!
