PROVE IT?
Most folks as soon as something goes wrong they blame the dog food.
Next it would be the Medicine.
Kidney faliure can be caused by alot of things.
Mostly when you turn a dog loose to hunt you don't see the dog for hours, even days sometimes.
If Your dogs died from kidney faliure (if this true) more than likely got it from you leaving ant-freeze out were they could drink it.
Clean-up your place and provide some real evidence before you stick your other foot in your mouth.

Question?
Does anyone have aLab or Bird Dog lost at 3-6 years old due to Kidney Faluire fromn Ivomec or any other Meds?
