Angels eyes should work for most dogs- perhaps you could try using more.

TBH I am now very Anti Angels Eyes- so much so that I think using it is dangerous- not necessarily to your dog in the immediate term but to all of us. Cross resistance in bacteria is on the rise because of inappropriate antibiotic use.

If you are unhappy with your angels eyes then demand a refund- not sure about the USA but here in the Uk credit card companies have liability- you have purchased a product that is illegal (in the USA) so they might be liable to refund you as a credit card company.

I recommended a product that worked for me, ie Angels delight but there are other safe and natural products such as the NaturVet tear stain supplement
