Good options to start with include sleeveless coats or jackets that fasten with straps across the chest and under the stomach. If you want to start even simpler, look for a large bandana that you can fasten around your dog’s neck.

As your dog gets used to wearing simple clothes, you can eventually work your way up to more challenging items, such as pull-on sweaters, hoodies, or full-body outfits that cover your dog’s back legs.

Make sure doesn’t have small parts that your dog could swallow, such as large buttons, since they could get stuck in its bowels. For most dog clothing, you will need to get a measurement around your dog’s neck (where the collar typically sits), around the widest part of the dog’s body (typically the chest, just behind the shoulders), and from the back of the neck to the base of the tail. Check the clothing labels to see if they offer specific sizing guidelines (e. g. , the weight, girth, and length ranges for which the item is appropriate). Look for items that are adjustable, such as vests or jackets with adjustable straps.

Even if your dog is already an adult, you may still be able to train it to wear at least simple clothes with a little extra patience and effort.

Continue to praise and pet your dog while it wears the clothing.

If your dog gets stressed out or upset when you try longer sessions, go back to leaving the clothing on for shorter periods of time for a while.
