Dogs being dogs is just something special
...flying ears, tongues, goofy faces...
However, you would have a hard time capturing these moments with a phone camera or even with an entry-level DSLR.
Freezing a dog mid-air requires not just professional gear (camera and lens) but also a lot of practice. All in all, it's easier to hire a professional, sit back, and enjoy the time with your dog than trying to create these pictures for yourself. I guarantee you both will have a lot of fun.
