It has been awhile since I had a dog. What are some of the no-no's to feed them? Are they lactose intolerant like cats? Chandelle tries to get at the milk I give my cat Beauregard. Beau loves milk and doesn't seem to care one bit if he is lactose intolerant. Also, the cats are not good at cleaning up all their cat food and Chandelle sure would like to help them out there. Currently I thwart that by putting their cat food on the picnic table where they can get at it but she can't yet....She is 9 weeks old.
