Pros: Patterns fit for larger dogs.
Cons: Patterns geared for novelty (purse dogs).
Finally, a dog sweater pattern book that has patterns that are fun and cute -- FOR DOGS LARGER THAN A CHIHUAHUA!
Don't get me wrong, you can knit something for your chihuahua or shih tzu, but you can also knit something for your Labrador or Rottie!
In my case, I have a shivering Pit Bull - Boxer! I have never had a dog with such a short coat -- she loiters by heating vents, pees right outside the back door, and now balks at taking a walk. So knitting her sweaters to wear constantly through the cold months was a necessity, not just a novelty.
Most pattern books are either made for tiny dogs (Jill Eaton's PuppyKnits is the worse - since when is XXL a dog that has a 10" chest?). Other books have patterns that just appear to be ill-fitting on the dogs in the picture. IF it looks that way on the picture (on well behaved dogs used as models), I can imagine how long it will last on a squirmy, energetic pup like my own.
The one negative is that many of the patterns are too impractical. They are too similar to the trendy Paris Hilton-type sweaters you see all over nowadays. The designer could have taken into account owners, like myself, who want to keep their dog WARM, not just in style!
