We will be getting 4 Nigerian wethers in a little over a week. We have a 1 1/2 year old lab and I'm wondering whats the best way to introduce them. Our lab is really good, he does have a tendency to chase our 2 cats if they start running in the back yard but he is just playing. He has never tried to growl, bite, hurt another animal. I just want to know what others have experienced with introducing new animals. Thanks
