Dog breeds info for collage project

[jahm2017]

I am trying to compile a list of basic dog size data for my collage project

As a starting point I am looking for information on

1. Breed of dog
2. Age
3. Chest circumference at widest point
4. Back length measured from collar to start of tail

Any stats provided will be much appreciated.

Thank you!

1. West Highland Terrier
2. 14 yrs
3. Do you mean around the rib cage? 14in
4. 16in

Really odd stats to compile for info on dog sizes. Breeds are normally measured by weight and height at the withers.

Rottweiler Cross (we think German Shepherd), 5 years old, 31" chest, 25" back length.
