Need some advice on potentially getting another dog
So recently my family have been thinking of getting another dog which i have no issues with because its their decision and we are not doing this out of an impulse decision, this has been a talk for awhile.
But we do have a reactive dachshund who is currently 2 years old and im a little worried to say the least. My dachshund was attacked by an off leash dog and since that incident, he has not been the same since. We are doing training and i am seeing improvements (yes we have those days but im taking it a step at a time).
My worries are im unsure on what is the correct way to introduce him to a potential new dog especially because it will be living with us. Im only worried because the last thing i ever want is for someone to get hurt and for the dogs to not get along. If someone has been in a similar position then i will appreciate the advice so much or if someone could give me tips on how to introduce them i will also appreciate that!
