I did this last summer. I left my other pet inside while I had my dog, Jax, put down on the front porch. The vet suggested I let her outside once the process was done and he had passed so I did so. She came up and smelled him and was for the most part okay, just timid. I can’t vouch for all animals handling it the same way but she was fine. I like someone else that commented used laps of love and would highly recommend the service to any pet owners. Jax hated the vet and got to spend his last moments at home in my arms. It was better for everyone involved.
