My 9 YO female has recently started scratching her stomach are (both sides). She would do it occassionaly and I'm not sure if it was the same spot, but now she's doing it more often. I notice it more when she firsts sees me, like after waking up in the morning or when I come back from work. On one side she has like a bump on her skin that a vet said was normal, without much examination. Could it be allergies, boredom? I'm feeding her TOWT with Nupro supplement twice a day. Thank you.
