Jack Russell constantly hungry
My 11 year old Jack Russell 'Molly' is constantly hungry and getting terribly overweight. She weights 8.5 kilos. She is well fed and was satisfied with 100 grams of canned dog food daily but now wants 200 grams and still hungry! Also has litte dog biscuits throughout the day that I'm trying to cut out. Has a daily walk but she is slowing down considerably due to her weight I think. What can I do because I am too soft and give in to her too easily, and that's not good. It's a problem. Thank you for any advice you can give me.
