Short answer: blueberries are a safe treat even when fed frozen, and around 5 berries a day is a reasonable guideline for a small dog.
Are blueberries a good treat for dogs?
Yes — they're rich in antioxidants, making them a go-to safe treat that can support eye health and healthy aging.
Is it okay to feed them frozen?
Feeding them frozen is safe, and they make a great cool treat especially in summer. That said, if they're frozen rock-solid, it can strain the teeth, so letting them thaw slightly first is a good idea.
What's the right amount to feed?
Around 5 berries a day works for small dogs, and medium-to-large dogs can have a bit more proportional to their size — just keep total treats under 10% of daily calories.
Does it really help with eye health?
Blueberries' anthocyanin content is known to offer antioxidant support that can be a helpful supplement for senior dogs' eye health. That said, it's not a treatment for an already-existing eye condition.
What should I watch for when feeding them?
Start with just 1–2 berries the first time and watch the digestive response, confirming there's no diarrhea or allergic reaction before increasing the amount.
