I have 2 Yorkies. Not specifically trained. Some days they stick to me like Velcro which can be annoying. I never thought about them feeding into my moods that way. Hmmm. I have thought about getting them a "therapeutic" sweater before. One would be a great help to have in my shopping cart, dr's office, etc.

When I vacation I prefer to not have them with due to stressors of hoping they will mind their manners in all respects at each person's place. They probably would. Just me.

Have had dogs all my life. They can sort out who's a nice person and who they don't care to be around. I pay attention and adjust myself accordingly.

Yorkies rock. They are very intelligent, shed like people and are good for ppl who have allergies. IMO excellent companions.

Best wishes.
