I am often asked what kind of hardware I use for my sessions. Well, I have one main camera body that I use; my Canon 7D Mark II (Canon EOS 7D Mark II Digital SLR Camera (Body Only)) and one go-to lens; my Canon 18-135mm (Canon EF-S 18-135mm f/3.5-5.6 IS Standard Zoom Lens for Canon Digital SLR Cameras).
Of course I have other lenses for different occasions. But the camera body and lens mentioned above are my primary pieces for in studio work.
As far as lighting goes, I prefer to shoot with studio lighting as opposed to natural light as it is more easily manipulated. I can get the look I desire just by adjusting a few settings on my camera and my lights. (Always in Manual mode on the camera).
I also use seamless backdrops in the studio of either white or black depending on the coat color of the animal I am shooting. Savage is the brand I use for my backdrops. (Savage Seamless Background Paper, 53" wide x 12 yards, Super White, 1) . The seamless does not become the final backdrop in the shot of course. It simply makes masking and editing a digital backdrop much simpler in Photoshop.
