thanks for the information,was given some calcium powder by the stud dog owner,to give to my bitch everyday,i had to stop giving it to her as it upset her tummy,is there anything else i could give her,in order to give her and her pups the best start,she is given a very well balanced diet,plenty of fish,chicken,veg,as well as her dog food(probably too much food,cant help spoiling her).when is the best time to add more food,i have lots of books on cocker spaniels and breeding they all seem to contredict each other :?
