I want to give some to Jade to see if she likes it but I dont know what to give her. Do you guys feed peanut butter straight out of a jar or is there peanut butter out there thats made for dogs...like the Kong Stuff'n Peanut Butter cans? Or maybe is there a brand that is better than the others? Also, how much do you give? Jade is only 5 1/2 or 6 pounds still so I know I cant give her too much, just wanna give her some as a treat every once in a while. Any help on this would be great, thanks!
