I will assume that the litter is registered, the bitch and sire are health tested and titled and this is a first litter in a bitch over the age of 2 and the bitch is in good physical shape. Maybe a lot to assume but there it is. I will just answer the question posed.How long between litters is recommended to wait breed again? And how many times do you reccomened. Trying to prove a point to a friend who's just had a litter.
A bitch can have a false pregnancy and/or pyometra on any cycle, regardless of whether she's ever been bred.It is healthier for the bitch to be bred back to back heats (normally they come in heat every 6 months). Leaving a bitch open for the next heat after having a litter also leaves her open for false pregnancy and pyometra and she may not catch on the heat after that. .
