I honestly didn’t think it was gonna work, but my golden retriever probably had the worst hotspot ever. He normally gets it on both sides of his neck and head. I normally have to shave him and I used a different hotspot spray before, and it only worked if I would shave the areas. I ended up buying this one this time thinking I would have to shave him and I didn’t this stuff worked. It started clearing up within the first 24 hours mind you it’s very small progressive steps. It has taken approximately a week to clear up, but I continuously spraying this spray on him every four hours I swear I was gonna have to go to the vet because he started not wanting to get up he got very lazy he was limping It really took a toll on him and mind you he is the most energetic golden retriever ever he’s only two years old and if you have a golden retriever, you know they are absolutely bat sh** crazy. Thankfully, for the spray he hasn’t been able to make a 90% recovery since I use this spray there’s still a little bit left to go, but I have confidence in saying that it’s gonna be all cleared up and if anybody was wondering the hotspot was on both back legs His private areas moving up to his rib cage it is spreading like a wildfire in this stuff, put a stop to it almost immediately. I’m very thankful I bought this. It has saved me a lot of money from going to the vet.
