Why don't we make a list of foods that dog's can't have?
I know of several and was discussing this at the dog park-I found it hard to believe dog owners (I would say good dog owners imho because their dogs were well trained etc) did not know about simple things like chocolate!!!
So here's what I know is toxic off the top of my head.
Add on, or dispute if you know them to be alright. Lets make a good list!!
Also -lets code them B for bad food (i.e. not toxic but not good to feed) and T for toxic (Feel free to add codes too

)
1) Chocolate -T
2) Black Licorice-T
3) Caffeine-B
4) Grapes/raisins -T
5) Avacodo-T
6) Cooked onions -T
7) Tomoto -B
8) Garlic-B/T?
Also some possibles? Tuna-b/c of the mercury content especially in smaller dogs?
