Ok, if this anomalia is hanging around dog neck, I assume these dogs will never be petting.
My opinion is, maybe the dog shouldn't be this owner. In my country, such activities are punishable. This is only my opinion and I received insults because of another topic.
First of all, I'm not from the US. I was answered under another topic that dogs that kill a chicken are placed on the neck of a dead chicken until it rots. I have never heard such a punishment on dogs in my life. I can't even imagine such an action. Is this true?
