Negligible Allergen Presence in Hospital Dogs After Washing.

Area of Science:

• Veterinary Medicine
• Allergen Research
• Healthcare Safety

Background:

• Allergies to dogs pose a risk in healthcare settings.
• Hospital Dogs are increasingly considered for therapeutic roles.
• Lack of patient-safe guidelines hinders dog integration in Swedish hospitals.

Purpose of the Study:

• To evaluate the efficacy of washing hospital dogs in reducing allergen levels.
• To determine the duration of allergen reduction after washing.
• To inform the development of patient-safe guidelines for hospital dog programs.

Main Methods:

• Dog fur samples collected pre- and post-wash, and post-interaction.
• Analysis of Can f 1 and Can f 4 allergens using competitive ELISA.
• Comparison of two different shampoos for allergen reduction efficacy.

Main Results:

• Mean Can f 1 allergen concentration decreased significantly from 21.8 ng/mL to 5.8 ng/mL post-wash (p < 0.0001).
• Both tested shampoos effectively reduced Can f 1 and Can f 4 levels.
• Reduced allergen levels were sustained for a minimum of three days.

Conclusions:

• Shampoo washing is an effective method for significantly reducing dog allergens (Can f 1 and Can f 4).
• The allergen reduction is substantial and lasts for at least three days.
• This research provides crucial data for establishing safe protocols for hospital dogs in Sweden.
