It depends on the breed of dog... not the size. Terriers are dumb and they are small and great Danes are dump and they are HUGE! Um. this is a comment not an answer, great Danes are the most majestic dogs in the world so next time you should now what your talking about i mean really!
they have to pump more blood through their bodies. They have a larger amount of blood that they have to move so it takes more to move the blood. this results in a faster heartbeat.
It will depend on the size of your dog. Larger dogs will need more food than smaller dogs.
More than likely, the dog is cold. Smaller dogs are usually more succeptiable to cold than larger dogs. Also the dog could be nervous or scared.
It is different at different locations but larger dogs will be more than a smaller dog.
They needed a more intelligent life form than you.
Larger dogs have some advantages over smaller dogs. They can be trained to do more complicated tasks that require size, provide better security as they appear more threatening, and children can play rougher with them as they're more resistant to their pulling and pushing.
Dogs normally don't kill people, but in rare cases of abused/provoked dogs, they may attack, and with some luck they may be deadly. Larger dogs are more deadly than smaller ones, but even giant dogs can be perfectly docile and friendly.
little dogs are more delicate, there brains are smaller than big dogs. big dogs are much dopier than little dogs. their brains are functioned which makes them more clumsy. littler dogs brains help them to be more agile, and help them take in their surroundings!
they are 20% smarter then dogs
smaller
A cougar print is larger and more rounded compared to a dog print, which is typically smaller and has a more oval shape. Cougars have larger paws with retractable claws, while dogs have smaller paws with non-retractable claws.
for my opinion cats are better. they eat less, excrete body wastes lesser and they are smaller. they can help eliminate rats around the house if ever there are and they are cuddly. for dogs, they can guard the house specially at night and when you are not around, they are friendly dogs are more intelligent that cats. I think dogs are better. They are more active and you can play with them outside more. I mean when was the last time you saw a cat park? There all dog parks.
