You can buy NuStock straight from the company in USA and it will give you the price in pounds. This product been around for a few decades. I have a great vet , he thinks out of the box and also for holistic if a customer wants to go that route. He also uses NuStock on his horses when they get cut, rashes etc.
@Manydogs mentioned once to me to use NuStock to heal my dog’s hotspot. My vet told me to shave around the hotspot, wash with dawn dish soap, dry it very well and add NuStock. Took a few days and it was healing well. And yes, it regrows hair! I eventually used it for any skin issues on all my dogs. It’s a product you need in a home if you have dogs. My way of building a dogs gut is with raw diets, fermented foods like sauerkraut as mentioned and organic bone broth. In your case, I would do them allergy bloodwork’s. It’s like very rare a dog can’t do at least one protein that would agree with their body. Bruno is only 2. He’s got a lot more years in him. Why I would get the blood test going and the NuStock with vet wraps and electrical tape!
