Hi Tasha,
You can also get Hibiscrub from the
http://www.hyperdrug.co.uk website I think its pretty cheap on there. I have a couple of our dogs who tend to be nibblers especially their feet. I use a combination of a small amount of malaseb about a tsp and 2tsp of Hibiscrub mixed together and diluted in warm water approx 1/4 pint. I wipe the affected areas every day, dry them then put on a cream which is fantastic its called 'Dermacton' it comes from a company called
http://www.aromesse.com it has a very strong lemony smell and is a perfectly natural product but they hate the smell and do not touch their paws all day with this on, its great for itchy, sore skin it also helps bring back hair growth after excessive nibbling.
