According to foreign media reports, there was a couple in the UK who wanted to raise a dog but had different opinions on how to raise a dog. The husband did not want a "big dog" because he felt that a big dog was too troublesome and the home was too small and inconvenient, so the wife went to claim a "puppy" behind her husband's back. She told her husband that the dog was a Jack Russell Terrier, a small dog, with a weight of generally 4 to 7 kilograms and a shoulder height of 25 to 26 centimeters. As a result, a few years later, the weight of this "puppy" actually reached 2 meters tall and 200 kilograms!

This is what the dog looked like when he first arrived. It's tiny, weighing only 1 pound 50 ounces (about 1.9 kilograms). The couple happily took care of it and named it Yogi.

When Yogi was 5 years old, her husband took the dog for a walk in the park. He was surprised to find that his Jack Russell Terrier was larger than all other dogs of the same breed.
