We do believe Muhammad(saws) was carried to a heaven by a creature of some type. It was something Muhammad(saws) had never seen before and never saw again. We do not know what it was except it was sent by God(swt). No where did Muhammad(saws) call it a winged horse.
Dog Memory Span. To be able to make a somewhat complete analysis about the span of dog memory, it is important to differentiate between associative memory and real memory. It is said that if a dog does not have some sort of exterior stimulus that he is not able to think about or remember parks or places he has been in before. But as soon as dog hears his owner's voice, smells him or perceives his presence at a distance, his associative memory activates or comes to life.
The life span of a dog depends on its size or breed. In general, the larger the breed or size of the dog, the shorter the life span. For example, in a study of lifespans, only 13% of giant breed dogs lived to be over 10 years old. Conversely, 38% of small breed dogs live to be over 10 years of age. Dogs are considered senior in the last 25% of their lives.
