It is a cat, not an owl: Crookshanks
Hedwig,his owl
No, Harry Potter's owl is named Hedwig, not Hedwig Twinkletoes. Hedwig is a snowy owl that serves as Harry's loyal companion and messenger throughout the series. The name "Twinkletoes" is not associated with any character in the Harry Potter books.
If you mean "owl", that would be Hedwig.
I'm not sure that the owl's gender is important, unless you are another owl. It certainly doesn't add to or detract from the story. However, the name Hedwig would suggest the owl is male.
Harry Potter does not have a dog, but he gets a snowy owl named Hedwig when Hagrid buys him one in Diagon Alley for his birthday during his first trip to Diagon Alley.
