Collars, toys, beds, grooming gear 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 personalized tags do well on Etsy, while bundles of grooming gear 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. Check your state department of agriculture's rules before your first sale, register where required, 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 leashes 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, leashes, bandanas and soft toys go in a poly mailer, 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 box, since a rolled bed often avoids a costly oversize box.
Kit for this step
Most accessory orders weigh under 1 lb, which keeps them in the cheapest USPS Ground Advantage 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 order 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 inches sells, and one that says "medium" gets questions and returns.
Accessories like collars, leashes, bowls, toys and handmade bandanas are the simplest place to start. Treats bring state feed rules, and medicines are off limits for a home seller.
Most pet orders are soft and light, so a poly mailer covers them. Beds and bulk bags of treats go in a box and need weighing before you list.
Straight answers to what sellers ask about this.
Often yes, but pet treats count as animal feed, and many states require you to register or license the product with the state department of agriculture before you sell. Labels need ingredients and a guaranteed analysis. Check your state's rules and the FDA pet food pages first.
Prescription treatments can't be resold, and most platforms ban pet medicines. Leave veterinary medicines to vets and pharmacies, and check your platform's prohibited items list before listing anything for parasites.
Whatnot, eBay, Mercari, Poshmark, Depop, Etsy, TikTok Shop and Facebook Marketplace ban or tightly limit live animal sales.
Pet toys aren't covered by the CPSC rules for children's toys, but you're still responsible for selling a safe product. Avoid small parts that snap off and squeakers that come loose.
Give the adjustable range in inches for neck and chest, plus the strap width. Add a breed example such as "fits most adult beagles" 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.
