Tried to play K9 photog today...........wish I would have had a Canon EOS 1-D and 24-70 F2.8 IS lens. Light gathering, focusing and drive speed can make a huge difference.
We had lost (had to put down) our two Beagles (brother and sister) after 17 years... Those two never moved without being side by side touching at the shoulder. Alice was full of cancer - so we put her down (too old to do much with according to the vet) and without Alice -- Elvis went to hell in 6 months! Like an old married couple!
