Hi everyone. I have 2 dogs - a one year terrier mix named Penny and a 4 year old pit mix named Kylie. Kylie is a rescue and was spayed about 6 months ago. Shes had at least one litter. For the last couple of weeks Penny has been licking Kylie's **** constantly. Kylie's bowel movements have been normal and i tried to extract her anal glands but nothing came out. She seems to be in good health but Penny's constant licking and sniffing has me worried. Any ideas or suggestions?
