Great Value Peanut Butter is safe for dogs since it does not contain any xylitol.
The ingredient xylitol that some peanut butters contain is what is harmful and toxic to dogs and it's a sweetener.
As long as the peanut butter does not contain any of the ingredient xylitol the peanut butter will be safe for dogs to eat and is healthy for them.
I feed my dog Great Value Peanut Butter sometimes and he loves it.
You can feed any peanut butter to your dog as long as it doesn't contain any xylitol.
