For the mastiff people who know some dogs leave paw prints on your heart… and some leave a whole legacy.
This one is for Diesel — a special memorial design made to honor a loyal best friend, a beloved part of the crew, and one unforgettable big dog soul.
Product Description
Please note: This exclusive That Guy With Mastiffs shirt is made to order and will initially run in 1-week pre-order intervals. The reason for this is because I do not keep inventory on hand, so blank shirts and DTF transfers will be ordered after the pre-order closes. Once everything is received then each shirt will be hand pressed by me with a commercial heat press. Awesome merch takes a minute — but I promise, they'll be worth the wait.
This official That Guy With Mastiffs memorial graphic tee is a meaningful design created for the followers, mastiff lovers, and loyal supporters who want to honor Diesel and the special place he holds in the heart of the crew.
Featuring Diesel with angel wings and the touching “A man’s best friend” wording, this design is a beautiful tribute to a dog who was clearly more than just a pet. It is heartfelt, memorable, and made for the people who understand that the love of a good dog stays with you forever. Sweet? Yes. Emotional? Also yes. Because some dogs deserve more than a memory — they deserve to be remembered out loud.
Customers will choose their unisex shirt color, shirt size, and preferred design placement option before ordering.
You may choose to either have the main design printed on the front with nothing on the back, or choose the option with the That Guy With Mastiffs small pocket-sized logo on the left front pocket area and the main design printed on the back.
Photos shown are mockups and are used for display purposes only. Actual shirt color, design size, and design placement may vary slightly from the listing photos because mockups are helpful little liars and real apparel has seams, sizing, fabric movement, and personality.
Perfect for mastiff lovers, dog memorial keepsakes, pet remembrance gifts, That Guy With Mastiffs followers, loyal supporters of the crew, everyday wear, and anyone who wants to honor a very special dog with love and purpose.
Part of the official and exclusive That Guy With Mastiffs merch collection, available only through Mastiff Mama Designs! Josh shares 25% of That Guy With Mastiffs profits directly with families of children and veterans working to get service dogs. Cute merch, big mastiff energy, and a purpose worth supporting. 🐾

• Blank shirts and DTF, Direct To Film, transfers are ordered after the pre-order closes.

• Once the blank apparel and transfers arrive, I begin pressing orders in the order they were received.
• Each shirt is hand pressed by me using a commercial heat press.
• Small imperfections may happen because these are handmade items, not factory-produced shirts from a warehouse with zero personality.
• I always do my best to make each shirt as perfect as possible before it heads out the door.
• Processing time may vary depending on shirt color, size availability, and current order volume
• Tracking will be provided once your order ships

Care line: Keep it cute, keep it cold, and please do not roast Diesel in the dryer like we are making an emotional support casserole.
Purpose
This listing is part of the official That Guy With Mastiffs × Mastiff Mama Designs merch collection, created for mastiff lovers who want more than just another graphic tee. This memorial design brings together big dog love, remembrance, and a purpose worth getting behind — because some dogs may be gone from our side, but they are never gone from the stories, love, and memories they leave behind.

The Unisex shirts go up to a 5XL size but only in certain colors. Occasionally, they go out of stock, and I am unable to get them in. At which point I try and order another similar brand that may have a different polyester and cotton percentage to them. I do my best to accommodate all of the sizes that I can purchase for my customers and offer the same rate for Adult Small-5XL.
