Anyone know what might be up with this? Sadie is a healthy 7 year old girl Beagle. She is very active and loves to snoop and sniff all over the back yard and loves to eat. She acts like she feels great, as usual. She does have allergies and itches a lot but we give her antihistimes for this. When we are cuddling her and we run our hands down her back or on her body petting her you can see and feel the muscles in her rib area ripple. Sometimes when we rub her like this she will take a back leg and try to scratch real fast. Anyone have any ideas?
