I tried 4 cones on Charlie in advance of surgery. A standard vet issue plastic cone An inflatable buster cone A kong cloud A soft cone - the brand name was "comfy cone" I went through the same procedure with them all. He got to sniff them, investigate them, then had them fitted with loads of treats, and got treats for being calm while wearing them. The standard issue vet cone was, well, just awful. It seemed uncomfortable, seemed to dig into his neck if he bashed it (which he did all the time), and was just jarring – on him, and my nerves. The fact he could see through it, seemed a disadvantage – in that it seems confusing for him. The buster collar was an inflatable ring, inside a canvas cover. I couldn’t inflate it. I checked, and although a footpump was available (gosh, it’s no bigger than 2 party ballons, why would you need a pump!) I couldn’t figure out why. In the end, after much examination, I broke a thin flim of plastic inside the valve with a knife. Then I could get it inflated. It was pretty rubbish though. I bought the large size, but Charlie could still eat a sea biscuit placed on his tummy. No way this was stopping him chewing a wound on his leg. The canvas was hard and scratchy and I didn’t like it much. I should have bought the extra large - at least. The Kong cloud was in response to the inflatable buster collar failure – maybe if I bought a more expensive version of the same thing? But no, sizing problems defeated us. To be fair, it was easy to inflate, and softer and more comfortable. It might just be because the sizing was difficult to judge, and I bought a size too small (so it wouldn’t stop Charlie getting to his leg, although it fitted round his neck ok). Since I could only buy it online though, I couldn’t check to try it in advance. The soft cone was a success. The online reviews warned me to buy a larger size (I bought large) and it was a good fit for Charlie. His standard collar (nylon, plastic clip) attached with sturdy elastic loops, which took a few minutes to adjust. He did bash things with it, but in a “soft” way, not a jarring way. The key thing was to measure the distance from his collar to his snout, and make sure the cone was longer – the online diagrams to allow me to do this were great and very helpful, allowing me to get the right size. He wears another collar behind the collar with the soft cone on, and this stops him pushing the soft cone collar backwards to get his snout passed the edge of the cone - it might fail without this though. It’s a big success. He tolerates it well, and it has successfully stopped him getting to his leg. He seems to sleep in it just fine, and treats it like a pillow. The one disadvantage was that there are a number of velcro strips that allow adjustment and two are left spare on the right size for Charlie. But there is only one "guard" strip, to allow the unused velcro to be covered up. Which means vetbed sticks to the exposed velcro. A trip to John Lewis haberdashery solved that though, with a strip of opposing velcro obtained.
