how to put weight on a 4 month old pup on raw food .Any suggestions please

Tripe and lamb (and lamb tripe is more fatty than beef tripe) are the fattiest raw meats. Just increase slowly though as too much fat can cause acid reflux in some dogs, and you want a balanced diet after all so make sure the dog is getting everything else it needs as a growing pup. :)

I have given her tripe and all the other raw feed she has put weight on but I have had photos of the rest of the litter and they look bigger.the problem is I don't want to overfeed her.all my other dogs are fine.

Do you really need to be adding weight at this age?  If you've got your portion sizes right then only minor tweaking should be needed to keep your pup at a good healthy weight as he/she develops.  Pups of this age often go from looking like waifs to barrels in a single meal!  There is a very good raw feeding calculator which should help - I'll see if I can find you a link :)

OK don't worry about pictures - they can be very misleading and there is often a huge difference between pups of the same litter.  Truthfully you might also find that some less experienced dog people/feeders may be allowing their pups to carry a little too much weight.  Those Andrex puppy adverts have a lot to answer for and not all puppies should be roly poly!!

Here is the Raw Feeding Calculator I mentioned

Yes I agree with Dogs a babe too, better to be on the skinny side (imo) than too heavy as joints etc are developing :) if your dog is healthy, happy, bright and energetic I wouldn't be too fussed with how the littermates look in comparison :)

Know how you feel though, I was paranoid about my youngest being too skinny as a pup! Filled out lovely now though.

thanks for all the imputs very much appreciated.We shall see what develops thanks

I feed a raw only diet to my dogs and my litters. I feed pups 2-3% of ideal adult weight per day and just keep an eye in case that needs a tweak. I'd rather have lean than chunky too quickly, as others have said more strain on developing joints. If you're happy you've got a good cal/phos balance then don't worry too much. it's likely her litter mates are being fed a little too much as it's such a common error.
