I had to put my 17 year old yorkie to sleep this past Saturday. The casket is so beautiful and the liner and pillow is such a nice touch for your pet. I got the small size. She was a tiny girl and was about 5 pounds. I was able to lay her on her side wrapped in her blanket, had 4 of her toys in there, photos and even a few dog treats. The small was plenty of room for her and her treasured toys. The casket comes with an adhesive tape you use to seal it up. I used the tape and also got white caulk to put along the casket as well. Very durable and I know my girl is now resting peacefully. I added a photo of her in the casket as well for reference. I hope this review helps someone else who is having to go through this difficult time with their pet. It never gets easier but this did help my grieving process.
