ok this last week I've noticed Bella having leg tremors.... She's now 19 months old. I did notice this when she was growing.... Just before a growth spert she would do this.... I only ever seen it in her front legs....last couple days I've seen it in both her front and back legs.... Isn't my girl a little too old to be having a growth spert now? Anyone ever seen this in their EMs before? Should I be calling my vet?
