Dog Tribute Tattoo

Tattoo Virgin here, and can't put more than one tag but on the topic of dog tattoos/tributes, is there a type of design that doesn't age well/quickly degrades moreso than others? I just lost my best friend of 16+ years and when I get her pawprint back I want to incorporate it into the tattoo.

I've seen the dog's face in their pawprint, the fine line outline of their ears, etc, I just wasn't sure if either of these would stand up to time or if there were better options. I'm going to redo my research on artists of course but I wasn't sure if a specific style would hold up better, what placement would do best and so forth to guide that forwards. I just want my best friend with me always.

Though she lost weight and changed appearance a tad would these be good reference pictures as well? I just want to make this as best as I can.
