What you can check fast.
01Start with the City basics
Mississauga requires pet licences for dogs and cats. Keep the tag visible on the collar and update the City if your contact details change, because the licence helps Animal Services contact you if your dog gets out.
02Set the health baseline
Ontario dogs, cats, and ferrets three months or older need rabies vaccination. For puppies, rescues, and rehomed dogs, use your veterinarian's schedule for vaccines, deworming, parasite prevention, and diet changes.
03Make the yard boring and safe
Check the latch, fence gaps, side gate, patio edge, garden beds, and any spot where a nervous dog might squeeze through. Choose the garbage-cart location for bagged pet waste before the first cleanup day.
04Build the cleanup habit early
Puppies and new dogs use the yard often. Picking up on a fixed rhythm keeps training areas cleaner, protects the lawn, and stops the first month from becoming a surprise spring-cleaning job.

Where does dog waste go at home?
Region of Peel lists pet waste as garbage. Bag it, tie it, and keep it out of recycling.
Is weekly cleanup worth it for a puppy?
