Hello! I was hoping you guys could help identify this bug, and let me know if it’s by any chance dangerous to our outdoor pets. At first I thought it might be a kissing bug, although I realize it is not. Thank you in advance!!  I meant to mention that it’s about a inch long, minus antennae.

Dear Alan,
This is a Longicorn or Longhorned Borer Beetle in the family Cerambycidae.  Though they are not poisonous, larger individuals do have very strong mandibles, and some species may draw blood if they bite.  The closest match we could find on BugGuide is Achryson surinamum, but we are not certain that is a correct identification.  We will try to contact Arthur Evans, an expert in Beetles, for assistance.

Arthur Evans provided us with a link to BugGuide and the identification of
Elytrimitatrix undata, the only member of the genus found in North America and whose “Larvae [are found] in var. hardwoods and pine”
