PrincessDiana | 02-23-2008 11:30 AM | Heartbeat Does anybody know how fast a dog's heart should be beating? I'm just curious because Franklin is asleep on my lap right now and I laid my hand on his chest for a second and his heart felt like it was going a million miles an hour! I tried to count and it was like 3-4 beats per second. Is that fast? It sounds fast to me, especially because he's sleeping. Shouldn't it be slower? He's been to the vet at least 5 times and they've never mentioned anything about his heart, so I wonder if I'm just being extra paranoid? :confused: |
