People in the northern hemisphere who can only see Canis Major in the Winter
are the victims of this drastic limitation because they're only willing to do their
stargazing for about an hour or two between dinner and bedtime.
If you're willing to go outside and see what's up at different times of the night,
maybe even while other people are fast asleep, you can see Canis Major from
the northern mid-latitudes at sometime during every clear night from about the
end of August until the middle of the following June.
From the south pole, you can see Canis Major in some direction 24/7 from March 21
until September 22, and you can watch it go around and around every 24 hours.
People in the US can see the constellation Canis Major only in winter because that is when the constellation rises in the early evening and is visible in the night sky. In the winter months, the position of Earth in its orbit allows for the best viewing angle of Canis Major in the northern hemisphere.
Canis Major is a winter constellation in the US because its location in the sky puts it in an area visible during the winter months. Due to Earth's orbit around the Sun, Canis Major rises and sets at different times of the year. This means that in the US, the constellation is best visible during the winter months.

Canis Major means "great dog". It was discovered by Ptolemy. It contains Sirius, the dog star. Sirius is the brightest star in the sky (after the sun). It has a right ascension of 7h. It has a declination of -20 degrees. 4 of its stars have planets. The "dog days of summer" are so called because Canis Major was visible during the hottest time of the year. It was sometimes considered as Orion's hunting dog. There is also a Canis Minor.
The brightest star in the night sky is Sirius, also known as the "Dog Star." It is a part of the constellation Canis Major and is visible from both hemispheres. Sirius is about 25 times more luminous than the Sun and is located only 8.6 light-years away from Earth.

The way the axis tilts and our position around the Sun has many contributing factors

as the earth moves around the sun,different parts of the sky come into view
If you know where Canis Major is, then you cannot miss Sirius. It is not only the brightest star in Canis Major, but the brightest in the night sky. Find Orion in the south, during the winter months in the northern hemisphere. Then find Orion's Belt, and follow its line of stars down to the left and you will find Sirius. It is unmistakeable. It is now April, but it is still visible in the early part of the night, but by next month it will be harder to see and won't be easily visible again until next winter.
None. The only two galactic object in the constellation are:- * M41 is an open cluster * NGC 2362 is an open cluster

Mainly because you only look at the stars between dinner-time and bed-time. If you're willing to go out and have a look during odd hours of the night, you can see Sirius and the other stars of Canis Major at some time before sunrise on any night after about August 15th. They reach the same position in the sky a little earlier each night than the night before ... by about 4 minutes each night. By the time the winter months have arrived, Canis Major and the other "Winter" constellations have backed up early enough in the night so that they're visible before bed-time.

Andromeda galaxy is approximately 2.5 million light years from the Milky Way however there is a dwarf galaxy discovered in 2003 named Canis Major that appears to be in the process of being absorbed by the Milky Way and Canis Major is only 42000 light years from our galactic core but only 25000 light years from Earth.
Because 1) it is a southern sky constellation and 2) it is in the daytime sky in Summer.
