I am planning on mating my bitch and was wondering what food people used to wean their pups on to. I have spoken with many people who have suggested a range of different feeds but wanted to ask all you experienced breeders on here. This is my first bitch (over 20 years of owning males) and want to give pups the best start I possibly can. I have a medium sized breed. Thanks in advance.

I buy Litterlac puppy formula milk and also have weaned my litters on burns mini bites mashed up in the litterlac.  Once they are able to I then start adding raw foods, cheese, sardines, meats, etc to give them the best start in life :) :)

you should wean them onto whatever puppy food you will be feeding mum in the last 3 weeks of pregnancy! usually this would be the puppy version of what she is on now.

I weaned mine on BARF from 3 weeks of age. Raw minced chicken/lamb/rabbit with raw veg mushed in a processor. By the time they were 4 weeks they were having a turkey leg to nibble on and by the time they had left they were on a full BARF diet at ten weeks, chicken wings/necks and pigs tails as well as their mince. I put two drops of ABIDEC childrens vitamin in one of their meals each day. Chicken wings should be hand held at first in case the pup tries to gulp, this way they learn to chew and eat slowly. I also fed them all seperately so as they didn't feel they had competition and ate too quickly. I gave a small saucer of goats milk after each feed and added a raw egg yolk in goats milk for supper. Snacks were raw carrots, sweetcorn niblets (not on the cob, can cause obstruction) sugar snap peas, chopped swede, pears, apples, melon etc.
Of course this is only applicable if you want to feed BARF - if not my apologies.

My two small terriers are also fed the entire range of BARF as well as my Malamutes.
