No. A small dog like a chihuahua has a much smaller brain than for instance a collie who is a much larger dog. Brain size does not necessarily have anything to do with intelligence though as both of the aforementioned breeds are relatively intelligent breeds.
yes they are
No
all dogs have the same size heart, that is why larger dogs live shorter than smaller dogs
Not exactly but I suppose try are all a similar size at adulthood
No, not all brains weigh the same. Brain weight can vary from person to person based on factors such as overall body size, genetics, and specific brain structures. On average, an adult human brain weighs about 3 pounds.
No, they do not, they have separate brains and therefore each has it's own reflex timing.
No, not all adult brains are the same size. Brain size can vary significantly among individuals due to factors such as genetics, sex, and overall body size. While average adult brain volume is typically around 1,300 to 1,400 cubic centimeters, individual variations exist, and size does not directly correlate with intelligence or cognitive abilities.
All dogs from the Moloser family has the same size and dogs don't have fangs they have solid k9s.
not all dogs grow to be the same size...so there is really not one answer for this question.
With a heart the same as you do... same as all mammals do.
Some brains are larger than others, and often a larger brain is connected with higher IQ. However, intelligence is more about the ability to make connections, and brain size would only increase the capacity for memory space rather than speed.
all dogs bark unfortunatley
