Personally I use an airhorn because this guy doesn't listen.
Because dogs can hear higher than humans, so it attracts there attention.
There are different types of dog whistles The most common one that people use is a very high pitched whistle that we can hardly hear but, as a dogs hearing range is higher than ours, they can hear it loud and clear ! They react to high pitched sounds and so you get there attention :)
yes. dogs have different blood types?
No, different types of dogs are made by different types mating (having sex) with each other.
Cats and dogs, it varies, there are different types of cats, and different types of dogs. I'd stay neutral on this even though I am a dog person.
We can not hear dog whistles because they are far too high pitch (they are out of our hearing range). However, dogs can hear this and they respond to it as if it was a regular whistle, returning to their owner or turning their attention back to the owner. Dog whistles are also designed not to annoy other people.
The dogs hear high notes very well, the sounds carry far, and it's easier than shouting.
No, they are different types of animal.
you don't get different types of carnivores
there are 45 different types of dogs in Australia
Nintendogs has different games with different types of dogs on them. Such as the Labrador & Friends game, which has Miniature Pinscher, Shiba Inu, and much more.
Because human beings like dogs and cats and keep breeding more different types.
