Questiondo you know how big a dogs heart is?!?!?!!ive looked everywhere & cant find the answer...
thx for ur time.
AnswerHi Lexi,
The size of a mammalian heart is approximately proportional to the body weight. So, a 50 kg dog has a heart that is 10 times as heavy as a 5 kg cat.
While I couldn't find an answer to your question either, in humans, the heart is roughly the size of a person's fist. So it's reasonable to consider that each dog has a heart roughly as large as it's own paw.
I guess if you want an absolute answer, you could call a veterinarian, and ask.
I hope I've been a help,
Patti
