HI Marcella. I will confess I know nothing about Pit Bulls! So I started searching for a pattern. I am not seeing A "Brindle" pit bull....what is coming up is a "Brindle French Bulldog". Is this the dog??!!
If you enter it in the upper left hand search box of this screen, you will find a picture of it...there is a pattern available for $9.50. Good Luck!!

If you type American Pit Bull Terrier into the search area at the top left of each page at this site, you will find a pattern by White Willow Stitching and also a leafler called Dogs Collection 9.
Neither are brindle. I successfully altered the colors on a White Willoe design of an American Bulldog, also known as ALAPAHA Amrtican Bulldog, very different than your Pit Bull, but the idea is that you can change colors to what you want. I did this for my daughter, in memory of her Ametican Bulldog. It takes some time, but both Pit Bull patterns look pretty good and could be adapted. I did an internet search and these two are the best!

An alternative would be to get a good photo of a brindle Pit and have it converted to a pattern. Be sure that the photo is not copyrighted. There are several sites that offer this service. You can just google "photo.to cross stitch pattern" and then you can pick one!
