dog is so flatulent lately

[garlicandsapphires]

She's been on Butternut box for a week and the flatulence has increased. Her poos are also often soft (sorry)
She never used to fart so much.
She was spayed a couple of weeks ago if that's relevant.

Should I persevered with Butternut box and hope it's just a change of diet, or assume that something's wrong with her tummy. She's in her usual good spirits otherwise.

Did you transition to new food over a period of time or just stop the old food and start with the new?

I have transitioned quite fast I suppose, but she can be picky so thought I'd just change it up. I will keep with the BNB for a while and see.
Thanks for answering
