An increase in licking or an excessive amount of licking may indicate that they have a medical problem, so it is important to see a veterinarian as soon as possible. The vet will examine your pet and may run tests to determine the exact cause of your dog's behavior and the best course of action.
When you take your dog to the vet's office, try to bring a stool sample if possible. This can be helpful in the event that they're suffering from an internal parasite. For something more straightforward, such as impacted anal glands or parasites, your vet can help immediately by expressing your pet's anal glands or by prescribing medicine to eliminate the parasites, respectively. Infections and parasites require immediate treatment. If your dog has an infection, they may need to take medicine and may also need to wear a cone to prevent them from licking the infected area as it heals.
If your vet can't determine the source of the licking, they may recommend additional testing to determine whether your pet has an allergy. If this is the case, talk to your vet about potential therapeutic pet foods that might be able to help alleviate some of their allergy suffering.
As a loving pet parent, you naturally pay attention to what type of behavior and activity is typical for your furry friend. If you notice your dog licking their butt more than usual, take them to the vet to help them get relief.
