Called my sis,
Robi, to get her take on paw probs. She swears by a silver salve (!) for animals which she says is a panacea more or less. Sounds a little bit dodgy to me particularly after hearing about the health hazards for silversmiths, but admittedly I don't know enough about that to hold an opinion so I'm just quoting her. She washes the area with silver water (silvervatten) before applying the salve (silversalva). They're not saying on the site that the silver salve has healing properties or even that it's for the paw, they're just saying it's antiseptic and prevents bacteria and fungi problems from developing, but sis seems to be saying the salve heals as well. There is a paw salve (tassalva) as well in the same line of products, which they say keeps the paws soft in order to prevent cracks. Prevention only, and sis didn't mention that one, I don't think she's tried it.
here's the page "V�lkommen in" = welcome (click), "Produkter" = products, and "Kontakta oss" = contact us. I'd be happy to help further in any way I can...
...oh sh!t, I just ran a search for colloidal silver (which is what they use), seems you could turn blue and all sorts of issues... look up "argyria" in Wikipedia if you're interested... any-hoo, I'll help you get it if you do want it after all - if all else fails.
