Collars, toys, beds, grooming kit and treats. Buyers want sizes, materials and proof it suits their animal.

Each step in the order you'll need it.
Dog accessories have the widest audience, then cats. Handmade collars, bandanas and personalised tags do well on Etsy, while bundles of grooming kit and toys suit Whatnot and TikTok Shop.
Pick one animal and build depth in sizes before adding more. A full run of dog harness sizes in one style beats a single size in ten styles.
Pet food and treats count as animal feed. Register as a feed business with your local council before your first sale, and keep a record of every ingredient batch you buy.
Reselling sealed, branded treats is simpler than baking your own. Check the dates on stock and rotate it so the oldest sells first.
Lay each collar or dog harness flat beside a tape measure and photograph it at full stretch and fully closed. Photograph clips and buckles close up, since buyers worry about a dog slipping free.
A photo of the item on a real animal sells better than a flat lay. Use your own pet or a friend's, with a calm background.
Live shows suit bundles and mystery bags. Squeeze each toy for the microphone and stretch leads on camera so buyers see the length.
Keep a sizing card on the desk with neck ranges for each dog harness size and read from it when buyers ask. It saves guessing on air and cuts returns.
Collars, leads, bandanas and soft toys go in a mailing bag, folded flat. Ceramic bowls need bubble wrap and a box, with paper filling every gap.
Compress a bed by rolling it and strapping it with tape before boxing it. Measure the packed size, since a bed often fits a medium parcel band once rolled.
Kit for this step
Most accessory orders weigh well under a kilo and fit a small parcel band. Weigh treat bundles each time, as tins and jars push the weight up fast.
Pet owners buy again when the animal grows or a toy gets chewed. Add a card with your shop name to each parcel and keep the same sizes in stock.
Each one costs you money or reviews, and each has a fix.
Complete kits for one kind of seller, costed and laid out.

Pet buyers shop by animal and by size. A dog harness listing that gives chest and neck measurements in centimetres sells, and one that says "medium" gets questions and returns.
Accessories like collars, leads, bowls, toys and handmade bandanas are the simplest place to start. Treats and food bring council registration, and medicines are off limits for a home seller.
Most pet orders are soft and light, so a mailing bag covers them. Beds and bulk bags of treats go in a box and need weighing before you list.
Yes, but pet food is animal feed in law, so you register with your local council as a feed business before you sell. Labels need ingredients and a feeding guide. Ask the council's trading standards team which rules apply to your recipes.
Prescription treatments can't be resold, and many shop treatments can only be supplied by a vet, pharmacist or registered animal medicines adviser. Leave veterinary medicines to pharmacies and vets, and check your platform's restricted items list before listing anything for parasites.
Whatnot, eBay, Vinted, Depop, Etsy and TikTok Shop ban or tightly limit live animal sales. Selling pets as a business also needs a licence from your council.
Pet toys aren't covered by the toy safety rules for children, but they still have to be safe under general product safety law. Avoid small parts that snap off and squeakers that come loose.
Give the adjustable range in centimetres for neck and chest, plus the width of the strap. Add a breed example such as "fits most adult cocker spaniels" to help buyers picture it.
Yes. Wash covers, photograph any wear, and say whether the item has been in a home with smokers or other animals. Buyers with allergic pets ask.
