Right now I am pretty in love with the cute, brilliant little Aussie puppy beside me! So my answer might be a bit skewed lol. But honestly I had such a great weekend with a whole crew of adult Aussies, and this puppy and her littermates are so amazing, that right now I would probably be happy if they were all I was ever allowed to own again.
But I want more Tollers too, and maybe a fluffy Belgian someday a long time from now and I still love C/Koolies too. Otherwise, not really a big desire to own anything else in particular. There are some other breeds I think about but who knows if I'd ever actually seek one out.
