Sophie is just over 3 months old. It's terrible to watch. She will get off bed, take a few steps. hack, go back to the bed. This goes on and on every 3-4 minutes for what seems like forever. I only harness her, and when this happens she has NO Harness, no nothing on her at all. It seems to be at the end of the day and after her "Hyper Hour".
Vet does not say much but I will push for an answer this month when we have our normal visit.
