How much benadryl liquid can I give my 14 pound Maltese for itching
I prefer benadryl anyway.

Benadryl can be given at a dose of 1mg per pound of body weight. Keep in mind, Benadryl tablets and liquids come in different sizes. So, an approximately 25 pound dog can get a full 25mg tablet or a half of a 50mg tablet. I usually avoid the liquid Benadryl in larger dogs (you would have to give too much of it). You can give Benadryl every 8-12 hours.

With liquid, if about 2.5mg per ml, then you could give about 5-6mls of liquid. That's a touch more than 1 teaspoon. You may be better off giving a 1/2 tablet instead.

If unsuccessful, you may need to get into a vet to determine if there is a allergy or other cause that requires better therapy. Only about 30% of dogs do any better with itching on antihistamines.

Good Luck

The benadryl bottle says 8ounces or 237ml so how much then of the liquid
It should say how many mg per ml on the bottle.

8 ounces is only total volume of bottle.

If children's benadryl.

Then the dose of a little more than 1 teaspoon is correct.
