Today I noticed my pup is walking strange , I got suspicious and called the vet , he says this is perfectly normal since it grows so fast and that I should keep walking him about a kilometer daily divided in 2 walks morning and evening , he only told me to give him more calcium in his diet , I'm not quite sure if this should be it so I'm asking you guys who had this problem with almost 3 months old pup and what to do and what not to do tnx
