Concern About New Spot on Dog's Snout and Other Ongoing Issues

Reader's Question:

Question from Alan:

Should I be concerned about a new spot on my dogs snout? 8 yr old. Licks paws and floor constantly. Was on a homemade diet of ground turkey, rice, pumpkin for a year, but that didn’t change anything. He is always been skittish around people and noises. The right side of his face has been paralyzed for almost a year, and the muscles slowly have tightened up. I just noticed this spot on the right side of his snout and the very top right edge of his nose.

What the Spot on Your Dog’s Snout Could Be and What to Watch For

Alan, thank you for your detailed question and for sharing clear images. From what I can see, the spot you’re referring to appears to be a small, raised, slightly discolored area on the right side of the snout and top edge of the nose. Given the context of facial paralysis and chronic licking, there are a few potential explanations to consider:

1. Nasal or Muzzle Dermatitis

• This could be a localized case of dermatitis, possibly from contact irritation, constant licking, or rubbing.
• Dryness, inflammation, or even minor trauma (like bumping into something) could cause a new lesion to appear.

2. Allergies (Environmental or Food-Related)

• Chronic paw and floor licking strongly suggest underlying allergies, especially environmental (e.g., dust, pollen, household cleaners).
• The homemade diet may not have addressed potential allergens, and some nutritional imbalances over time could affect skin health.

3. Skin Growth or Lesion

• It’s possible the spot is a benign growth
  like a papilloma or sebaceous cyst, but it’s important to rule out something more serious, such as a mast cell tumor or infection.
• Growths can appear subtly and may change shape or size over time.

4. Secondary Effects of Facial Paralysis

• Facial paralysis can lead to changes in muscle tone, drooping or tightness, and reduced movement or sensation, which could increase the risk of unnoticed trauma or skin issues.
• Uneven grooming and reduced muscle mobility on the affected side may also contribute to skin irritation or debris buildup.

What You Should Do:

• Schedule a Veterinary Checkup: Any new lesion or spot on the nose or muzzle area should be examined—especially with a history of facial nerve issues and ongoing licking behaviors.
• Consider Allergy Testing or a Prescription Diet Trial: If allergies are a persistent issue, a vet may recommend either testing or a prescription limited-ingredient or hydrolyzed protein diet.
• Monitor for Changes: Keep an eye on the spot for any growth, color change, ulceration, or discharge—these would warrant immediate attention.
• Reduce Environmental Triggers: Try minimizing exposure to scented cleaners, air fresheners, and certain fabrics that could be irritating.
• Address Anxiety or Compulsive Licking: Behavioral support, such as enrichment, calming supplements, or a prescription medication (under vet supervision), may help reduce compulsive licking if anxiety is a factor.

Your attention to changes and thorough observations are very helpful. Since your dog already has some complex health issues, I strongly recommend having your vet examine this new spot to determine whether it needs further testing or treatment.
