How to treat a sore on paw picture attached

[Itsbeenalongoldday]

My lovely black lab 7yo with arthritis in his paws amd front should has been constantly licking his back foot over the weekend and has caused it to look pink and sore. Is there anything I can do to treat at home?
he was on librella until around 2 months ago but has changed on to pills for the pain. He’s on previcox and memantine. He didn’t seem to lick so much on old regime but I agree with vet that librella might be doing more harm than good. Any advice welcome ?

We've also got a black lab, they're the best aren't they. Our girl had a sore on her paw that just wouldn't heal, despite everything the vet tried.

After lots of research, I bought some medical grade Manuka honey, put that on the sore, covered and padded it with sterile gauze and then bandaged with self clinging bandage. I put fresh honey and gauze on daily. Within a few days, it was hugely improved and all healed with a week.

I've just re-read your post and now am wondering if it was more the pain relief your were asking about - sorry if I've misunderstood. Have you tried acupuncture or hydrotherapy? Both worked really well for our last lovely girl.

If you want to keep it covered the vet wrap bandages are good or a sock. A cone of shame would stop him licking it and give the skin time to heal. Vaseline if the skin is sore would help. Just really to stop him licking more until you can get a vets appointment to change his pain relief.
we’ve had older labs on paracetamol (normal human stuff but not liquid paracetamol as other ingredients are toxic) and some on loxicom. Vets don’t like prescribing loxicom longterm but it depends on the age on the dog. Current one on it is 15.

Many years ago a PDSA nurse told me to use Sudocreme on sores and 'hot spots', then wrap it to stop them licking it.

I expect the advice will have changed now but it did work.

Sudocrem was suggested to us, we did try a tiny bit but apparently zinc can be toxic in larger amounts so I didn't dare slap it on.

Thanks everyone I don’t think he in pain as not whimpering and very active still but then he’s stoic.
I think maybe a vet visit / email is in order as don’t want infection to set in
it would be so much easier if like people you could take them to a pharmacy !
he is going hydro and it’s their pain mgt specialist who’s suggested this new regime. We up one of the drugs next week now we know he doesn’t have any adverse reactions.
i think he is self soothing with the sucking noise I hear him making when he not licking anything
so hard when they can’t speak !

If you don’t think he’s in pain just cover it to stop him licking it. If the skin isn’t broken it won’t be an infection risk.

I've always had black Labs. The first one had a hot spot/wet eczema several times. We had to use Hibiscrub a couple of times a day then a cream from the vet. These days I would Hibiscrub and tea tree cream. You want to stop him licking it whatever.
