Query: Angels Eyes for tear stains in pets

Angels' Eyes Tear-Stain Eliminator for Dogs, 120-Gram BottleI would not advise use of this product as it carries an antibiotic. Long term use of this can cause health problems in pets. Tylosin is an antibiotic in the Erythromycin family, it uses this as a titrater. I do not believe long term use of this product is healthy for your pets.
