Fleetwith Romper Rip Repair?

My 4 month old teething puppy snagged the pant of my brand spanking new Fleetwith Romper just below the pocket and I am so upset! This is the first new garment I have bought since the start of this pandemic and it was a splurge. How do I repair a rip in this type of fabric?
