My 10 month old, ~25kg golden retriever puppy has been sticking his butt on the floor and walking (as seen in the video). He also has abrasions on his anus. I stay in a small town and unable to reach out to a vet at the moment. Can someone please help me out?

Hi Vinod. That’s referred as scooting and this behaviour is seen when a pet is either having worms in stomach or when there is an infection of anal gland. Preferably, try to go to a veterinary hospital nearby for the proper examination and diagnosis or book an online appointment with a vet on kuddle.
