Photoshop a dog in to a picture

I am looking for a skilled Photoshop artist who can seamlessly incorporate a dog into an outdoor scenery. The dog should be interacting with specific elements in the picture. I want the dog to hold my husbands hand and it has to look real. If it does not look real then I won't buy. This is a very important photo for me and I want it so bad. Its a wedding picture outside and I will also send a photo of the dog. The preferred style for the edit is realistic. It does not matter which of these three photos it will be, you can choose which one is best.

Requirements:
- Proficient in Photoshop
- Experience in photo editing and manipulation
- Attention to detail to ensure a seamless integration of the dog into the picture

Skills:
- Advanced Photoshop skills
- Ability to create realistic edits
- Strong attention to detail
