Just tried this product this past weekend. Rita's allergies kicked into high gear and she developed an irritating spot around her armpit. We sprayed the Blu-Kote and not thinking let her in the house. We ended up with blue spot on the floor that would not wash out. Needless to say be sure the Blu-Kote is dry before letting your dog back into the house. The product did help her itchy sore spot heal.
