Ok my sister's dog is around 7 and when she was about 6 months old im guessing, she got mange. We have treated her and treated her and treated her, she's been on meds her whole life, but she just can not shake it. We don't have the money to do constant vet visits and meds anymore. Does anyone deal with this? What do yall do to help keep the mange at bay? She eats as much as our german shephared and our german shephared is a little over weight, but she is really skinny. Just want to help her out more
