I wanted a design that clearly said “Big Sister” with a cute and playful font. Some shirts also have paw prints, hearts, or dog-themed graphics, which I thought added a nice touch. Consider whether you want a simple look or something more colorful and eye-catching.
Durability and Washability
Since my dog loves to play and get messy, I chose a shirt that is machine washable and durable. Check the care instructions before buying to ensure the shirt can withstand regular washing without fading or shrinking.
Price and Value
There are options available at different price points. I balanced cost with quality to find something affordable but well-made. Sometimes spending a little more upfront means the shirt lasts longer and stays looking great.
Where to Buy
I found the best selections online, especially on pet specialty stores and marketplaces like Etsy for custom designs. Local pet boutiques also sometimes carry unique options if you prefer shopping in person.
