Many of the steps mentioned under 'Immediate steps' will help treat symptoms that a Maltese may be suffering from. This includes an allergy shampoo, and quality coat care sprays.
If allergies are minor to moderate, you may want to speak to your vet about giving Benadryl to your Maltese. While this will not cure allergies, it can provide good temporary relief. The standard dosing is 1 mg per each pound of body weight, i.e. 5 mg for a 5-pound Maltese.
To improve skin and coat health, an Omega 3, 6, 9 fatty acid may work, when given for 1 to 3 months.
Many Maltese that have moderate to severe allergies will need to be seen by the vet, not only to try and pinpoint the triggers, but to also receive prescription medications.
This often includes
Antihistamines. Types most commonly give include Benadryl, clemastine, chlorpheniramine, or hydroxyzine.
Topical hydrocortisone for localized itching.
3) Topical antibiotics will be given for any areas that look to be infected.
For severe issues, steroids including cortisone or prednisone may be given.
If steps taken at home cannot result in avoidance of the allergen trigger, 5 months have passed with chronic symptoms, and other treatments are not controlling allergies, immunotherapy may be suggested.
With this, a dog will be given skin tests to check for hypersensitivity. Once a trigger is identified, altered antigens are injected on a slow and steady basis. These are given either weeks or months apart, depending on the type. This helps a dog to become desensitized to the allergen and can be very effective. Up to 80% of dogs show marked improvement.
