A couple of my pointers for general dog photography...
It is easier to shoot a dog if you have someone handling the dog for you. Often the owner is best because the dog is most comfortable with that person. I will often recomend a show lead on the dog because it provides some security but is very narrow and easily Photoshopped out.
I most often use flash both indoors or outdoors. Indoors, I will shoot with a multi light-setup such as this (this one, is for small size dogs). BTW, I will set up my lights using a substitute such as a stuffed animal or statue. I cannot expect the dog to have the patience to wait for me to fool around setting up lights...

For quickie shots, I will bounce a flash modified with a Joe demb Flash Diffuser pro... IMAGE LINK: http://rpcrowe.smugmug.com …631943&k=cJ2BGfn&lb=1&s=A
I like to use a fairly long lens because I don't want the dog's nose to seem elongated. IMO, long lenses are as flattering to dogs as they are to people. My favorite dog (and people) lens is my 70-200mm f/4L IS.
I also like this lens for action shots. I will use AI Servo and burst mode. The focus capability of my 7D really stands out in this type of photography... IMAGE LINK: http://rpcrowe.smugmug.com …187351&k=xkc4nps&lb=1&s=A
Another tip is to try to shoot from the dog's eye level. I am an arthritic old geezer; it hurts like heck to bend down and if I kneel, I might not get up. My solution is to pose the dog on a higher level such as this retaining wall... IMAGE LINK: http://rpcrowe.smugmug.com …91845006&k=MoAMk&lb=1&s=A
Additonally, be cognizent of your background. Selective focus is one way to enhance a background and to draw attention to the dog,,,IMAGE LINK: http://rpcrowe.smugmug.com …721830&k=ZTkkrdC&lb=1&s=A
By the way, IMO, shooting more than one dog increases the difficulty geometrically, especially with puppies. Having helpers can be a Godsend... IMAGE LINK: http://rpcrowe.smugmug.com …91865496&k=Y8vA3&lb=1&s=A
Use something to attract the dog's attention. I like to use a plastic squeeker which is designed to be sewn inside a squeek toy. These squeekers can be found in craft shops (Michael's has them for twenty five cents). I put a squeeker between my teeth and squeek by clamping down. That way I have both hands free to handle my camera and when the dog is attracted to the squeek, it looks straight into the camera...
Finally, high noon is as bad a time to photograph dogs outdoors as it is to photograph people.
