In my opinion, vetericyn is useless. Is sterile water and some chemicals. I don't believe it's harmful by any stretch - but 99.9% of all wounds will heal up correctly with NO intervention. Vetericyn just likes to claim the credit for it.
I had a cow deglove 1/4 of her udder. Severed veins; bled all over. Lost gallons of blood. She got 25 stitches. I sprayed it with alushield that night and again in the morning. Ran a hypertonic saline IV so she'd rehydrate herself. Dried her off that next day, tossed her on a pack that was clean and dry - my sum amount of medical care for her. No antibiotics, no scrubbing, no hosing. Just a 'hey you're not dying' check every morning. In 2 weeks I couldn't pick her out. In 2 mos when she freshened I couldn't see the scar even.
I'm a "horrible person" I know for doing next to nothing. But if I had sprayed vetericyn on it daily it would have been a vetericyn success story!
Sometimes we'd amputate a toe (also called a claw) on a cow. They'd get it wrapped immediately after and a single shot of excede (antibiotic). The next day the wrap would get cut off. She'd stay on a dry pack for a week or 2: if the milker thought about it he'd hose it off. Our success rate was over 80%. The failures often had the other remaining claw in worse shape than initially thought and couldn't walk on it. None had complications from infection. Once again, I'm a horrible person for doing next to nothing, but if I had sprayed vetericyn on it daily it would have been a success story!
I can go on for hours with stories like that.
My main point is though, people fuss wayyyyyyy too much with wounds on animals in my opinion. To the point where it slows up healing. It WILL heal. It won't stay open and ugly forever - a lot of people forget that and aren't patient.
Vetericyn is a $40 bottle of water. I do however like their eye gel. It's soothing. I've used it on myself even. But I don't think it CURES anything. I don't even keep blukote around. Just a cheap tattoo gel to help soothe the really ugly boo boos and burns.
