My dog licks the floor a lot. Is it normal? How can I make her stop?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach! There can be medical reasons that would explain this behavior or boredom, stress or curiosity. I would recommend having Snow's feces tested for parasites to ensure this is not the problem, as specific treatment is needed to treat different intestinal parasites. A blood panel may be suggested by the veterinarian as well. However, with Snow's age this is likely a behavioral problem. Floor locking is a common self calming behavior. I would consider dog day care once or twice per week or hire a dog walker if you do not have time. If Snow is alone at home, you can relieve the stress or boredom by using safe dog chews or interactive dog toys such as the Kong toys. I hope this helps! Please let me know if you have any other questions or concerns!
