my one female dachshund is my"love bug" she loves everyone; the other female is totally oppsite with some fear aggresion but just the barking part; she is very shy and backs away from strangers. we are working on it and she has gotten better; before on our walks she would bark at every one but now she can walk without alot of barking; I use the command "STOP" and make it sound sharp/louder. I have now 4 ; just adopted my first real rescue. My other 3 are all semi rescued; people gave them to me because of various reasons. My older male 2 1/2 has fear aggresion also but, towards men; except my husband; he has gotten better and now tolerates my grandson(22) and loves my great grandson, but I am still cautious with him around strangers. So my new one is 18 months male; have had him for a week now and he already knows the doggie door(have flap taped up) and ramp, runs around and loves to roll in the grass; the other 3 are ignoring him but starting to come around and play a little; he has a close attachment with his crate; but I guess that is to be normal.
