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.
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.
Some chihuahuas grow to be able to fit in your hand at adult size and a dachshund is usually small.
A girls. Dogs hair might not grow at a noticeable rate in some breeds.
the same way we grow, small to large!
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.
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 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.
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.
