my doxie sucks

Question
I have a four year old male doxy and he sucks his sister's ears.  Her ears have NO hair on them and now she has sores from his intense sucking.  They are litter mates and he has been sucking since they came to us at six weeks of age.  Please help.  I feel bad for my little girl with the sores on her ears.

Answer
You can use anything that will stay on, to wrap his ears with. Vetrap would work well, too. Just don't do it too tightly. You don't want to cut off circulation to his brain! Ha ha!
