Neo's are known for having growing pains, Ultima my 5 month old has had them for about 3 weeks now, at first i was worried so i took her to the vet and had her x rayed, nothing showed up. I am giving her vitamin c, sure grow, and msm. I wasn't keeping her seperate from Alliseaa who is 10 months and they would get to playing pretty rough, so now i am keeping Ultima kenneled most of the time. The breeder, (co owner) said she should be ok. Have any of you went through growing pains with your pups?
