The Bark has grown into one of the most trusted and recognized dog magazines on the market. It started as a newsletter in 1997.  They require robust features about nutrition, behavior, wellness, and adoption for dog lovers.  They are seeking feature articles and short how-to pieces with a word count of 600.  They also like fiction, essays, and poems.  Pay rates vary, are based on the length of the article, and are negotiated.  They pay for online submissions with a one-year subscription to their magazine.  Read their submission guidelines here:  https://thebark.com/content/submission-guidelines
