That depends: if he is a purebred, he can get any where from twelve to fifteen inches. If he is not, then, who knows.

The first place you should try is your local humane society. With all the animals in shelters I think it is irresponsible to get a dog (or any pet) from a breeder. There is probably a Jack Russell waiting for you there right now.
Jack Russell terriers are known for being very active dogs. This may be normal for her, however a veteranarian can examine her for any possible problems such as a urinary tract infection which would cause excessive urination.
Jack Russell terriers can adapt to apartment living if they receive sufficient exercise and mental stimulation. They are an active breed that requires daily physical activity to prevent boredom and behavioral issues. Regular walks, playtime, and mental challenges are essential to keep them happy and healthy in an apartment setting.

Any dog has the capability to kill a mouse if it has not been trained to control itself. Many dogs just bark at mice and other potential quarry. Terriers are especially bred to be "ratters", i.e. they will chase and hunt down rats and mice. Some terriers have better instincts for this than others, particularly the Jack Russell terriers. They are quick, agile and intelligent, but easily bored if not continually given mental or physical stimulation.
Unless the Jack Russell was bred with a Golden Retriever then no, it is not physically possible. If your Jack Russell has given birth to Golden Retriever puppies, then clearly, your dogs magic. The only solution.
Jack Russell Terriers may hop on one leg as a playful behavior or a way to express excitement. This characteristic is often seen during play or when they're trying to get attention. Additionally, it can be a sign of their high energy and agility, traits that the breed is known for. If the hopping seems excessive or is accompanied by signs of distress, it might be worth consulting a veterinarian to rule out any underlying issues.
