A Wart on my yorkies ear

Question
I have a yourkie who is about 18lbs, not fat but a larger than normal yorkie.  He has all of a sudden gotten a wart on his ear and it is getting larger.  How can I safely remove it or does this have to be done by a vet

Answer
18 lbs is overweight for any Yorkie. Males rarely make it to 15 lbs.
Any kind of growth on a dog's ear should be removed by the vet as the ears will bleed and bleed and then you will have a huge mess.
So better than starting that, just schedule an appointment and have it removed by vet.
