When my dog goes outside to urinate, she'll pee. Then she'll walk a bit, squat again like she's peeing. She does this for seveeral minutes. The urinte is always light yellow-that's never changed. She's a 4 year old border collie cross with food and environmental allergies. She's fed Natural Balance Potato and Duck as per vet. She also has bad hips, being treated with over the counter glocusimine, missing link vitamins and her food as per my holisitic vet.
