Here is some general Bull Terrier toy information about sizes and other facts worth to consider
Be prepared to spend some money on toys for your pooch, because English Bull Terriers need diversion or pretty soon they will be up to mischief. If you own a Bull Terrier for the first time, it will not take you long to find out that although they need plenty of exercise, just walking them will not be what can really please or exhaust this breed. In fact, many English Bull Terriers do not even like walking very much.
Chasing after a ball until they drop – well, that’s a whole different story.
Also many of them are (excessive) chewers. This is why you can’t just give them any toy. You will have to make wise decisions and likely have to look for toys in the upper price range.
In general, and this is especially true, if you have a dog with a dismembering habit or a puppy, you should never leave your dog completely unattended and without the possibility of your immediate help (for example in case of choking) while it is playing with toys. Also with most toys ingestion of larger pieces could cause trouble to the point os surgery. Therefore ingestion is something we want to avoid as owners.
