I'm a Collie gal. Most intelligent dogs on the planet. And the most eccentric at times, in my opinion.
Adore Collies. Have had two, both males, both sweet and wonderful dogs. Perfect dogs for children too.
My last wonderful Collie, Blaze, a rescue, had seizures toward the end of his life and it became very difficult for me to handle him on my own. I had been married when I had our first Collie, Kelly, so hubby could lift him if need be.
However, it was so difficult to handle Blaze at the end, I decided would not get another large dog. Of course, that did not mean I did not do everything I could for Blaze and luckily my neighbor was a male nurse who was always wonderful about assisting me if I needed to get Blaze into the car.
However, since him, I have stuck with dogs I can pick up and carry, but I have been so tempted many times to have another Collie. Absolutely fantastic dogs.
