Was out walking last week with the lurchers and my wee bitch went away for a while, when she came back she had inch cut cut on her leg, its not deep or wide open, had been wiping it down with salty water each day but from last week her legs swelled up and shes lost a bit of weight, brought her in the house lastnite, there was a lot of puss coming out her leg, got her on antibiotics and keeping her in the house for a few days, any ideas on this to help it more
