Yes. Strawberries are safe for dogs and most of them like them — the sweetness appeals to dogs the same way it does to us. They're also one of the more nutritionally reasonable fruit treats you can give: relatively low in sugar compared to something like a banana, decent source of vitamin C and fiber, and a high water content that helps with hydration.
Remove the green tops before serving (not because they're toxic, just to keep things tidy) and cut them in half or quarters for smaller dogs to avoid any choking concern. That's basically the entire prep process.
A few things to keep in mind
Strawberries do contain natural sugar, so don't go overboard. A couple of strawberries for a medium dog is a treat — not a meal supplement. Dogs with diabetes or weight management issues should get smaller quantities or skip it in favor of lower-sugar options like blueberries or carrots.
Fresh strawberries are the only format that makes sense here. Strawberry jam, syrup, and processed strawberry-flavored products are full of sugar and often contain additives your dog doesn't need. Some "sugar-free" versions may contain xylitol, which — as with peanut butter — is a real problem for dogs. Fresh, plain, that's it.
Frozen strawberries are fine too. A small frozen strawberry on a hot day is actually a pretty good treat option — low calorie, cold, slightly chewy. Most dogs who like fresh strawberries will take the frozen version without complaint.
Nothing complicated here — strawberries are one of the more straightforward fruit questions.
