Generally they don't, but if they do it is normally due to cataracts or some other disease in the eye which causes them pain. therefore you could have the dog humanely put down or have the eyes removed.
Some people think its cruel to have the eyes removed but i know a Jack Russell that has had its eyes removed, and other than the occasional bumping into things, it has a perfectly normal and healthy life.
If the apartment or condo is small then no. Jack Russells are very hyper little dogs and need lots of space to run around in. I have one and she is very hyper. So Jack Russells arent really good in apartments or condos.
Jack Russells are great with children and and are very easy to ptty train. They need a walk about 2-3 times a day and lots of exercise. The backyards can be good and bad. What is coll about the backyard is that they can play with the kids and get good exercise, but what is bad about it is jack russells tendto dig holes in the ground.
Jack Russells, being a very high strung breed, really need to be taken for walks daily, giving them enough time to run and play, and just smell new things.
During any puppys early stages of life they should not be doing to much exercise. but thats not to say that they dont need any exercise. A puppy under the age of 6 months will probably need two/three walks down the road and back up and maybe a run around in the garden in between :) Jack russells are very energetic dogs and once adult then a good run around the nearby park in the morning and a brisk 10-20mins walk in the evening will do good for him/her !
Jack rabits have large eyes because they are prey animals. They need the ability to see far and wide so they can detect they're hunters.
Tires can be removed from vehicles by first placing the vehicle on a jack. You will then need to raise it, and with the use of a tire iron to remove the lug nuts, the tire will be able to be removed from its axle.
They are called floaters and they go away after a few minutes but may need to be surgically removed.
Jack Russells are very energetic dogs. Living around 15-20. Usually these dogs will have their buzzing energy right till the end of their lives. They need lots of exercise otherwise you can find your Jack Russell is training you! rarther then you training him! But Jacks make one the the best family pets, loyal, trusting, happy and very trainable animals. They will love you till the very end of their lives.
Jack it up (make sure to use jack stands), remove tire. I assume you are talking about front rotors as the back is a drum. There are 2 12mm bolts on the back side of the caliper that need to be removed then the caliper should be easily removed from the rotor. At this point the rotor will just slide off the hub.
It really depends on the dog himself. You will always need to keep them apart, because even a small dog can hurt the hamster on accident. Some dogs, like Jack Russells, were originally bred to catch rodents in barns, so their prey drive might be stronger than other dogs.
Any dog can be a pain if you are not ready for them, not responsible for their needs, or don't take the time you need to with them. That aside, Jack Russells are smart and energetic. This means that if they are not burning off all the energy they need to, they WILL think up another way to use it. Just their idea of fun, may not be your idea when they have to do it themselves. They are eager to please their owners, and are able to learn a lot of tricks with a little time spent. My brother's Jack Russell would roll over on his back with his tongue hanging out if you pointed your finger at him and said bang. They are the type of dog that you have to spend that kind of time with. They need the play and interaction. If you are able and willing to have a little best friend that you spend time with, then they are awesome dogs.
Same reason as humans do. They need their eyes to see.
