I was thinking it is perhaps a Vaccinium, but I don't think it is that. V. arboreum has very small berries and the leaves are (generally) smaller in shape and redder in fall color. Of course the ones in Arkansas might be different than the ones in Georgia. What about Gaylussacia, Huckleberry? The plant may be too tall for huckleberry .... I believe that counting the number of seeds helps to distinguish huckleberries from blueberries. Huckleberries supposedly have 10 seeds whereas blueberries have more.

Just a guess based on your description. Could it be a Nyssa? Here is a link that might be useful: Nyssa images

to guess height... put a 6 foot shovel against the trunk .. and retake the second pic.. a bit further away ... so you see the whole tree.. then use the shovel as a scale ... gets you pretty close ... though i doubt that info would be of any use here.. just a trick ... in case you are stopped in the street some day, and asked how tall a tree is... lol ..... have your shovel with you .. and can snap the pic ... BTW .. if the dog already ate them.. isnt it a bit late ... lol .. dog are pretty smart, about not eating bad things ... you cant really eradicate every threat to the dog ... there might be some odds... the fruit is or has fermented ... you might be better concerned if she has any alcohol tendencies... lol ... the leaf damage reminds me a lot of what i call fireblight on my older crabs ... but i dont think that term is correct .... but those arent crabapples ... ken
