Markers for determining the biological age of a dog

A computer system for determining the biological age of a dog, comprising:

• a. a processor;
• and
• b. a memory storing algorithm that, when executed by the processor, cause the computer system to:
• i. receive first and second inputs relating to the dog, wherein the first input is selected from the group consisting of blood globulin, blood total protein, blood alkaline phosphatase, blood platelet count, blood mean corpuscular volume, and urine specific gravity, and wherein the second input is a size category of the dog;
• ii. compare the first input of the dog to a reference value stored in a training dataset comprising inputs of the size category of the dog;
• iii. generate, based on the comparing, an output comprising the biological age of the dog;
• iv. display on a graphical user interface a customized recommendation comprising an exercise regimen based on the biological age of the dog.
