Our dear little Lokii we got from DogsontheLoose.com knows where he should pee, but every now and then he misses the mat. And the sharp lingering urine smell is unbearable and it sometimes irritates my eyes. German Shepherds are my favorite dogs ever, but they´re so big! I have tried every scented products out there, but even the costly ones designed for dogs seemed useless. A friend suggested I use an orange oil-based cleaner, and believe it or not, it worked! The oil neutralized the pungent odor for half the price of a professional pet product.
