Q/A: Size of a Pomeranian Brain
According to the first chart below, a dogs’ brain is approximately 1/125 of his total body weight. Since an adult Pomeranian weighs in at roughly 5 pounds (breed standard is between 3-7 lbs), the weight of a Pomeranian brain should be “about” .65-.70 ounces (or 19-20 grams). For comparison, your “average” small egg weighs about an ounce and a half. So, if the Pom’s brain is similar in density to a small egg, the “size” should be something like 1/3 of a small egg (a brazil nut size - maybe?).
| Species | E/S ratio | Species | E/S ratio |
| small birds | 1/12 | lion | 1/550 |
| human | 1/40 | elephant | 1/560 |
| mouse | 1/40 | horse | 1/600 |
| cat | 1/100 | shark | 1/2496 |
| dog | 1/125 | hippopotamus | 1/2789 |
| frog | 1/172 | (Kuhlenbeck, 735) |
Note that a cat’s brain is 1/100 it’s body weight. A 7 pound (3300 gram) cat has a brain roughly 2 inches (5 cm) in length and weighs about 1 ounce (30 grams). It would seem the cat should be “smarter”. However, according to this chart
| Species | EQ | Species | EQ |
| Man | 7.44 | Cat | 1.00 |
| Dolphin | 5.31 | Horse | 0.86 |
| Chimpanzee | 2.49 | Sheep | 0.81 |
| Rhesus Monkey | 2.09 | Mouse | 0.50 |
| Elephant | 1.87 | Rat | 0.40 |
| Whale | 1.76 | Rabbit | 0.40 |
| Dog | 1.17 | (Macphail, 243) |
which measures encephalization quotient (EQ), the dog “slightly” beats the cat. The conclusion would be that brain weight does not necessarily equate to intelligence. Interesting.
