Thank u very much for replying.I forgot to add though that the 2 of us and the 4 dogs,our 2 cats,stray cats and kittens that moved under our mobile home and other stray dogs are all living on my husbands social security check,$1,100 a month.With all the other expenses everyone else has,morgage,truck payment and all.We just can't afford that stuff if their going to eat.There's just no money for it.At least their fed well and no longer homeless and out in the bad weather.Looking for a home cure.The last dog we took in,our neighbor said he put clean motor oil on her hind legs is why she no longer has it there.I'v always heard of it and figured it was just an old timers tail.I had it work on a stray I took in a long time ago for a small spot on her face.Thought someone may have suggestions along that line.I do appreciate your response though.
