We’ve all seen it: Fido, scooting his rear end along the carpet, dragging his nether regions across the floor. It’s not a pretty sight (and not a pretty smell.) Why on earth would Fido scoot, scratch and drag his tush? Scooting is unsavory to say the least, but it is also a frequent topic of conversation between clients and veterinarians. The truth is, there’s a short list of irritants that can cause Fido to have anal pruritus (an itchy rear). Impacted anal glands are the most common culprit for this problem, followed by allergic dermatitis.
