Just figured I would share something I learned lately. I noticed that Archer had been licking his paws more and more, and that the fur between his toes was turning red. His feet also also had that "corn chip" smell, and his skin looked a bit red. It almost looked like it was itching or bothering him as he was starting to spend a lot of time doing it.
I switched him to raw food, though, he is still on the same protein, chicken, and I also spoke to the vet when we were there for something else- and she recommended a shampoo and some paw wipes. She said with the red staining it was likely Malasezzia yeast, and that in 80% of the cases washing the paws regularly with the shampoo (Malacetic) would clear it up. Well sure enough after a couple of weeks and a couple of washes with this stuff his paw licking has really reduced. You have to let it sit on the paws for 5-10 minutes, but Archer doesn't mind just standing in the sink eating treats.
I wanted to take care of it before it became too much of a habit or before he got a lick granuloma or something (my friend's dearly departed Corgi had HUGE issues with paw licking to the point of raw sores so any sign of it starting is kind of terrifying to me now). So it could also be the switch to raw food as well (less starch in the food means less fuel for the yeast), but, he did start licking his paws again more recently, and we washed his feet with this stuff and it calmed down again.
So for anyone who is wondering if their Hav may have an issue with paw licking, may I suggest you consider that it could be a yeast issue on the paws and look at some of the specialized shampoos. There are also some available online called Malaseb I think, which is very similar.
Part of why he had the problem could also be that we are often in and out in very wet weather here in Vancouver, so his feet were frequently moist. Dry feet apparently are less likely to have this issue.
