Please help, its the sake of my dogs!?!?

There is not much you can do about Tasha being blind, and many dogs are living wonderful, happy lives while being blind. Her skin irritation, as well as Tia's fleas, can be easily fixed using antibiotics (Tasha) and a flea treatment (Tia). This should not cost more than $200. Are you old enough to work? Maybe ask family members or friends for some money help? If your dogs are in pain they cannot continue to suffer. If you cannot find the money, you need to think of what's best for your dogs and find them a home that can afford to keep them healthy and happy. It's difficult, but suffering is a horrible way to live.
