Here's why:
* Red bumps and itching could be many things: allergies (food, environmental), parasites (fleas, mites), infections, or even just dry skin.
* A vet can diagnose the cause: They'll examine your dog, possibly take a skin scraping or perform other tests to determine the root of the issue.
* Treatment varies based on the cause: Medications, special shampoos, dietary changes, or environmental modifications are some options.
In the meantime, here are a few things you can do:
* Keep your dog calm: Don't let them scratch excessively, as this can worsen irritation.
* Clean the affected area: Gently wash the bumps with mild, unscented soap and water.
* Avoid irritants: Wash bedding, consider using hypoallergenic cleaning products, and limit exposure to potential allergens.
It's important to note: If your dog's bumps are accompanied by swelling, fever, lethargy, or difficulty breathing, seek immediate veterinary attention.
Remember, your vet is the best resource for diagnosing and treating your dog's condition.
