Doppler heartbeat monitor

Has anyone hired the Doppler fetal heartbeat monitor from Fit and Fertile and if so, did you think it was any good ?

not something ive used but pretty sure nick and cath cowie have one they use! worth asking them?

Hi there. I've 'answered' in another post, but here's my 'take'.

Since I'm very far from a vet, I did purchase my own doppler. I found it very good. Could do a head count from week 6, and counted 4 pups, at one point 5. After 3 puppies were eventually born, the mom seemed to be 'finished' whelping, and I used the doppler on her. Could clearly hear another heartbeat inside. so we administered oxytocin, and last pup were born.

Afterwards I've read that sometimes you pick up a major artery from the dam, and can confuse it with a pup. So I suppose if you scan 10 times, and get one 'different' reading, go for the 'avarage' . Thus if you picked up 4 heartbeats 9 times, and 5 1 one time, I'd go for the 4, as this was what was picked up most of the time.
I guess with bigger litters it might become more tricky.

Currently I have a 'supposedly' pregnant bitch, but did not pick up any heartbeats yet (today is day 36) So either she's NOT pregnant, or it's to early still.

Will update again.
