Sorry to hear about your dog passing.

If you have your heart set on a collie, how about an older one from a shelter? that way you wouldnt need as much exercise as a pup would which might be more manangable.

Is there any other breeds you like the look of?

www.dogbreedinfo.com

I find this site useful for infomation about different breeds.

Would you consider adopting or would you definatly want a pup?

www.petfinder.com is a good website for shelter dogs if you are cosidering that option

Let us know what happens!
