If your Havanese has a foul odor coming from her backend or is constantly scratching her rear on the carpet and licking excessively then she may need to have her anal glands cleaned. A dog’s anal glands are sacs that secrete a smelly liquid each time she poops. The odor is unique for each dog and can serve as a way for your dog to mark her territory. Sometimes the anal gland can become impacted, which is usually when you start to notice the smell or see your Havanese dragging her rear end across the carpet. It’s important to call your vet or take your Havanese to the groomers for anal gland cleaning to prevent further impaction or anal gland disease. If you’re not sure about going to a groomer, just schedule a routine appointment with your vet. For more information about anal gland cleaning, consult with your vet Plano, TX.
