Time to face mask/spacer acceptance in dogs and cats

Aerosol medications are recommended for use in dogs and cats. Perceived pet intolerance to a face mask/spacer might prevent clinicians from recommending them, and thus prevent owners from using them. Our goal was to evaluate the duration required to train a pet to accept a face mask/spacer.

Pet owners with no experience using a face mask/spacer were recruited. Pet owners applied the face mask/spacer q12h and graded each attempt on a scale of 1 to 5, with 1 = "not tolerated" and 5 = "perfect compliance." "Compliance" was defined as the animal tolerating the face mask/spacer with minimal or no restraint for a duration of at least 10 breaths for 4 separate treatments over 2 d. Time to compliance and overall compliance were calculated.

Forty-four pets were enrolled and 43 completed the study. All dogs achieved compliance with a median time of 4 d (range: 2 to 18 d). Eighteen of 20 cats achieved compliance with a median time of 6 d (range: 2 to 19 d).

Habituation to face masks/spacers was easily achieved in dogs and almost all cats.

Concern over pet or owner acceptance should not be an obstacle to prescribing inhaled medications. Most animals could be habituated to a face mask/spacer within 19 d.
