Guinness is not himself today. Not sure if I should be worried or happy? He isn't eating the cat, he isn't chasing the birds, he isn't jumping in the pond he's sitting by our feet like an old man and actually listening and obeying all commands. This just isn't Guinness? I have noticed his stools are quite soft lately (we have over the last 2 weeks switched from Iams to Innova LB Puppy food). This food is supposed to be much better for him, but frankly he seemed better on the Iams ( now we have soft stools, huge movements and gas OMG!). Do you think the food is making him feel a little off?
