Our dog is 12 years old. We recently put her on CBD because of her arthritis and limping. She has always loved her walks (she gets 2 a day) but we noticed her energy went up after she started eating Dr Marty's dog food. She's a 60 pound dog and we can not afford to just feed Dr Marty's food only but we add 2 tablespoons as a topper to her regular food. She has a sensitive stomach but this food does not bother her. She is so excited to eat it!
