Since the end of July, she did not eat anything and consequently her weight just dropped off. Over the last week I have changed her diet completely (from dry food to tinned dog food with bread and biscuits) and her appetite has returned. Now her hair is breaking off from her back, it looks as if it has been cut off with scissors, there is no irritation. She was seen a year ago as she had hormonal problems.
Unfortunately I don't know what was diagnosed, but she had scabs under her jaw and on her back legs and an ear infection. She was treated with 2 courses of antibiotics and made a full recovery.
