Do any of you have tips for adding a new dog to the house? Our situation is that we have a 6.5 year old female (Domer) that has been our only dog and gets quite a bit of attention - goes for walks, rides, is with me most of the time I'm not working. I'm considering adding another female, 8 years old to the mix.

Both dogs are docile and can take or leave other dogs - no agression, but not crazy about them either. Our current dog, Domer, is an alpha type, the new dog is described as subordinate and is smaller than than Domer (20 lbs compared to 40 lbs).

Domer is a shelter puppy mix - probably some beagle, but could be lots of things. The new dog is a small beagle.

Any suggestions and success stories would be welcome.
