New Pet · Behavior guide

The first 24 hours

What's going on

Your new pet has just had a huge day. They've been moved, driven, possibly bathed at the shelter or sanctuary, and now placed in a brand-new home with brand-new humans and brand-new smells. Even the easiest, most adaptable animal is running on adrenaline. The first 24 hours are about helping them downshift.

What to try

Be a calm presence

Cancel non-essential plans for the day. Stay home. Sit with your phone, read a book, work quietly. Your new pet doesn't need entertainment. They need to see you exist and that the house is calm.

For a new dog

  • Arrival: bring them in on leash. Take them to their potty spot first, then in. Let them sniff their main room.
  • Food: a small meal a few hours after arrival, in a quiet spot. Don't be alarmed if they don't eat — many dogs skip a meal or two from stress.
  • Walks: short, leashed, around your immediate neighborhood. Skip the dog park. Skip the brewery patio. Skip the family barbecue.
  • Sleep: set up a crate or bed in a quiet area. Many dogs sleep deeply the first night — they've earned it.

For a new cat

  • Arrival: carry the carrier into base camp (the prepared quiet room). Place it on the floor, open the door, sit nearby quietly. Let the cat exit when they choose — even if it takes hours.
  • Food and water: available in base camp from the moment they arrive.
  • Litter box: in base camp, far from food and water, easy to access.
  • Hiding: expected. A box on its side or a covered bed gives them safety. Don't reach inside.
The first 24 hours are about safety, not bonding. Bonding has years to happen.

Resist the urge to share

We get it — you want to introduce your new family member to everyone you love. Resist. Keep visitors away for at least the first few days. No grandparents, no friends, no neighbors. The animal needs to know you are safe before they meet anyone else.

What to expect

  • Some dogs sleep deeply for 12+ hours. Some pace and pant.
  • Some cats stay under the bed for the entire 24 hours.
  • Skipped meals, soft stool, or loose stool from stress — common, usually resolves in a day or two.
  • Vocalizing — whining, meowing, yowling — especially at night. Stay calm; check on them; don't make a big deal.
  • Accidents in the house, even from a 'trained' dog. Not a discipline issue. It's stress and a new environment.

What to avoid

  • No baths the first day.
  • No big training sessions.
  • No 'meeting' other pets in the home — even through doors — until at least day two for dogs, and only via base camp scent for cats.
  • No leaving them alone for hours.

When to ask for help

Call your vet if your new pet is vomiting repeatedly, has bloody stool, refuses water for 24+ hours, or seems to be in distress. Otherwise, normal weirdness is normal. Reach out to us anytime with questions — we love hearing about first-night stories.
