Hot spots — also called acute moist dermatitis — are among the most uncomfortable skin conditions a dog can experience. They develop rapidly when a dog repeatedly licks, chews, or scratches a localized area, breaking the skin surface and introducing bacteria. Within hours, a small irritated patch can become a weeping, inflamed lesion several centimetres wide. Triggers include flea bites, allergies, ear infections, matted fur trapping moisture, and stress-related over-grooming. Prompt topical intervention is essential to stop the cycle of self-trauma and prevent the lesion from spreading or becoming deeply infected.
ImRex Phenrex Soothe Hot Spot Spray is a veterinary-developed topical spray formulated to provide fast relief from the itching and irritation that drive hot spot behaviour in dogs. The spray delivers antiseptic and soothing actives directly to the affected skin surface in a convenient no-touch application format — useful for dogs that are too sore to tolerate handling near the hot spot.
The 250 ml spray bottle provides a generous supply for treating active hot spots and using preventively on areas prone to recurring irritation (inner thighs, base of tail, neck folds). Regular application helps dry the moist lesion, reduce bacterial load at the skin surface, and interrupt the itch-scratch-damage cycle that makes hot spots difficult to resolve.
For best results, clip the fur around the hot spot before applying to ensure the spray reaches the skin surface rather than sitting on top of the coat. Apply 2–3 times daily during the acute phase, then reduce to once daily as the lesion improves. Prevent licking with an e-collar if needed during the healing period. If the lesion is deep, spreading, or not improving within 48–72 hours, a veterinary examination is warranted as systemic antibiotics may be required.

Supplement Advisor's Note
Hot spots that recur seasonally — typically in summer or fall — are often allergy-driven rather than purely traumatic. Treating the surface lesion helps in the short term, but identifying and managing the underlying trigger (environmental allergens, food sensitivities, flea allergy dermatitis) is the only way to break the cycle. For dogs with chronic hot spot tendencies, maintaining a consistent flea prevention protocol and addressing underlying atopy with an appropriate diet or supplement can significantly reduce frequency. Use Phenrex Soothe as your frontline acute response while working with your vet on the root cause.
FAQ
How quickly will the hot spot improve after using this spray?
Most dogs show visible improvement in the lesion's moisture and inflammation within 2–3 days of twice-daily application. The itch reduction helps interrupt the self-trauma cycle, which is key to healing. Lesions that do not improve within 72 hours may require veterinary treatment.
Can I use this spray on cats?
Phenrex Soothe Hot Spot Spray is formulated for dogs. It is not indicated for use on cats. For feline skin irritation, consult your veterinarian for an appropriate product.
Do I need to clip the fur before spraying?
Yes, clipping the fur around the hot spot is strongly recommended. The spray needs to reach the skin surface to be effective. Applying over a thick coat significantly reduces contact time and efficacy.
Should my dog be wearing an e-collar while using this product?
An e-collar (cone) is highly recommended during the healing phase. The spray addresses the irritation, but many dogs continue licking due to habit or residual itch. Preventing further self-trauma is as important as the topical treatment itself.
Is this the same as the Phenrex MVD kennel disinfectant?
No — they are different products with different formulations and intended uses. Phenrex Soothe is a topical skin spray for dogs with hot spots. Phenrex MVD is a diluted environmental disinfectant for hard surfaces (cages, kennels). Do not interchange them.
