the only thing i will say is (obviously not for full shaves) but espescially larger breed double-coated dogs and some larger terriers are notorious for hot spots, and sometimes shaving down is the only option. My year-old berner got a terrible hotspot on his tail this summer and the only option I had was to get his entire tail (except for a little poof at the top) completely shaved off by my vet.
That’s different! Medically required shaves are fine, even though it sure does suck when they grow back wonky. And hot spots suck in general - I’m very glad that isn’t a problem Dan has ever had.
At least in some of the terrier breeds, the hot spots are frequently caused by food allergies, so once a diet that doesn’t bother them is found, they go away. No allergy, no itchy skin, no mucking with it to make a hot spot. My friend had that issue with her bully mix - turns out she can’t handle a large amount of chicken. Feeding a varied diet from the start can decrease the risk of allergies developing, so I plan on rotating proteins for Future Dog since they will likely be a bull terrier.
If the hot spot is due to grass/pollen/other plant allergies, it’s harder to do away with them entirely since dogs need to go outside, but allergy medicine can help reduce their symptoms and decrease how often they form hot spots. The same goes for hot spots triggered by itchy insect bites. Until they make a preventative that keeps EVERYTHING away, there’s always some risk they’ll get bitten and then work up a hot spot trying to chew it away. Which, fair. . . I’ve been known to cut open bug bites so they stop itching. . .
And then there’s hot spots caused by dampness. . . I can relate to that, too. I have to blow dry my hair in summer because it remains humid too long if it doesn’t thanks to the moister air, and then I wake up itchy. I don’t blame dogs for tearing themselves apart - they can’t dump tea tree oil on their spots like I can.
