Bloody Women, always leave you high and dry!!
I reckon you have it down about pat Coops, an injection of calcium when she first starts helps and then some oxytocin to clean her out afterwards also. The vets usually sell it as a whelping kit, I'd ask a Greyhound vet mate!
Have some rubber gloves, and old towels there to clean the pups as their born as there's shit going everywhere!!
All the best mate, whens she due?? Whats the breeding??
