not as much as some dogs do but there again all dogs need excercise.
All dogs, especially small ones, need lots of space and light. They also need access to clean water and ventilation. They also need as much exercise as large dogs, and can get aggressive if not trained and treated like a big dog.
Belgian sherperd, lots more don't have time, but not all dogs
all dogs are social animals so their at least need a human friend. Pugs are highly affectionate so their need lots of attention from they owners. pugs need a dog friend only if their are left on their own for a long period of time.
All over, they have no particular habitat requirements, other than being with people, and other dogs and cats. They need lots of exercise.
all dogs are healthy unless they get a disease or something.
Well, dogs make weird noises for all sorts of reasons, they usually make noises if they want something like food or to be let outside. When dogs make weird nosies it is just like when we need to say something we talk, dogs bark or make a noise.
Of course you can. You need rules and discipline. Above all you need lots of exercise. Dogs are much more receptive when they are depleted of excess energy. It makes training much easier.
Dogs should not be banned from the city. But big dogs shouldn't be in the city. They need lots of space to excersis. If u can provide that it should be ok. Small dogs would be better for the city. Cities like New York is bad for all dogs. The air isn't healthy for them and they need room to excersis. Though not as much as big dogs.
All of them! they all need love and attention.
animals can do lots of jobs. dogs are used as guide dogs and drug sniffers, some are used for magic shows and circuses and there are lots more. there are probably lots more than that but it would take forever to list them all. so that's all the jobs i can think of.
All dogs need and want company. If you feel that you won't have enough time to devote to your chihuahua, you should get him a companion dog so he won't be lonely. if they dont have people the will destroy
