My 3 yr. old beagle mix (female) has had some greeting issues for the last three days (she has been outside in her pin). Every time a person would walk up to look at stuff or if just passing by she goes nuts. Barking, jumping and howling. I have tried everything including muzzle (this has worked in the past), mixing vinegar and water and spraying it around her and doing what works inside; just telling her the quit down. I do not know if it is because she fears of something happening me or if its just that she wants all the attention.
