I have 4 great pyr puppies who are 1 month old today. They have had a rough start and are bottle fed pups due to being abandoned by the breeded because his dame didnt priduce any milk. They have coccidia, and are on their 2nd round of meds for that. And take another dewromer at 2 weeks and 4 weeks. Im worried our pups arent weighing enough. Does anyone have any clue about weight at 4 weeks. The weights are 4lb 8 oz, 6lb 2oz, 6lb 15oz, and 7lb 6oz. Also they throw up sometimes, especially the little one. We have taken them to the vet on 5 diffrent occasions, which is very expensive. Any one ever dealt with this before?
