Aquanita,
I am a dog lover too, so I am always looking to bring something for my buddy Max!
So in each of the theme parks there will be a section of one of the larger stores that will have a pet gift section. It typically has everything from chew toys, clothes, leashes, food and water bowls, and other great items. The location has been in flux lately in some of the parks, so the best thing to do is get in to one of the stores and ask one of the cast members where to go. But at last memory, the one in the
Magic Kingdom was in the stores along the left side of Main Street U.S.A. as you enter the park.
There is also a great store with Disney-inspired pet items at Disney Springs. The
Marketplace Co-Op – Disney Tails has a lot of the same items, and sometimes more. It is not huge, but I found the selection to be very good. There is also another store at Disney Springs that has pet items, the
Happy Hound. They are not typically Disney-themed, but they have some inventive items you may not have seen elsewhere.
I hope that this helps, and that your four-legged friend enjoys the gift!
Have a Magical Vacation!
