Hi, there is so many cocker spaniels out there already, ask your self why you want to breed? will you be able to keep all the puppies if you have too? will you be able to affored a c - section if needed? will you be able to supply the mum and pups with the bedst care / food ? (take into account you have to triple and then some the bitches food)? are you willing to hand raise the puppies if need? do you have homes already lined up for them?
if so find a suitable stud dog who has EXPERIENCED handlers that COMPLIMENTS your bitch.
there is so much more than putting two dogs together and gettings puppies, timing is important and there is a LOT of risks and things that can go wrong, is it worth maybe loosing your bitch over it??
then you'll need :
whelp box
heat box
gloves
disenfectent
vet after hours number
gloves
string
blankets
car full of petrol incase you need to get to the vet
puppy cage
and LOTS more
also be prepared to have NO sleep a bitch and pupipes shouldnt be left alone for atleast the 1st 4 weeks
then after that they are a real handful!!
