Big dogs have a lot of hip and joint problems. The bigger the dog the harder it is on their joints. When people get older they stop jumping around and carrying on...most dogs don't.Also it is hard on their backs. The longer the dog (great dane for example) the more space between his front and back legs. Also, there are a lot of big breed dogs that are prone to neurological problems too. Its a shame, I love big dogs. Also having to maintain a larger body is harder on all parts of the body, like their heart and other organs. They are the ones who usually get Arthritis and have intestinal problems. There is just so much more strain on their body. Little dogs don't have such a large body to maintain and usually have less issues having to do with their organs and their bones.
2nd Answer:
Some of the larger breeds are prone to cancer and heart problems, such as Great Danes tend to have heart problems, Bullmastiffs tend to have cancer, etc. It breaks your heart to own a large breed as they pass on way too soon.
Because their major organs work a lot harder to sustain them than a small dogs vital organs, and therefore are under much more stress through out the dogs life. That's why they generally age faster.
Larger dogs age faster for some reason than smaller dogs.
Another contributing factor may be that small dogs are often "indoor pets," more pampered and protected from the elements than big breeds, which are more often "yard dogs" or working dogs.
They have a faster metabolism than humans, all of their biological processes occur quicker. The opposite occurs in long living animals like tortoises which is why they age slower.
In ancient times dogs did something bad so a curse was put on them. BAM!
Ben Richarson - Big dogs feel nicer ( if you kniow what I mean)
if their the same age no but if the big dog is older then the small one yes

Of Course They Do! Real Life Dogs Start As Tiny Little Puppies. They Grow Into Large Dogs!
yes the large intestine is really large.
How long a dog's tail grows really depends on the breed. Many large dogs have tails about a foot long. while small dogs have tails that are usually about 5 inches. Dogs tals grow as they grow, rarly exceeding the length of their back.
the same way we grow, small to large!
A girls. Dogs hair might not grow at a noticeable rate in some breeds.
No, they are not as large or as wide.
Most sheep dogs grow to be medium to large depending on the breed of sheep dog. Some, like corgis, are relatively small (they weigh anywhere from 25 to 30 lbs) and others, like beaucerons or Old English Sheepdogs, are large (they can weigh close to 100 lbs.)
Personally, I would choose Purina's Beneful for Small Dogs. I think it has all the vitamins and nutrients a small dog needs to grow and stay healthy. If its a puppy, get the Beneful for Puppies.
They don't. They just seem to grow faster, because it takes less to double the size of something small. In terms of actual organic mass, older trees grow faster.
All dogs stop growing when they reach physical maturity, regardless of breed. Some breeds, such as the Great Dane, develop into very large dogs, while others, such as the Chihuahua, develop into very small dogs.
They look large because the puppy is so small, similar to how kids look when they get their permanent teeth before they grow into them. But as the puppy grows, its ears will grow more, but not as much as its body will.
Teacup dogs are simply runts. They are intentionally bred to be smaller. Unfortunately all the health problems of being a runt go along with that. They do grow just as all puppies grow, they just start out less well developed and don't grow as well or as large as healthy pups.
