I ‘d be off to the vet to ask someone who has dealt with this before. Make sure all is well- usual dog foes. If clear, great! No, that doesn’t mean you must buy the expensive food from the vet’s office. (Not with as many special blends available.)Your canned food may be too rich for the dog’s tummy. My dog’s stomach was ‘iffy’, so I tried canned food for weight management. It doesn’t have all the rich additives which caused the upset. Keep some dry in the diet somehow- treats and such. Helps keep strong teeth. Vet first though. Have a sample of upset diarrhea,AND regular. Also watch to see if doggy eats grass and such when outside. Good luck. Pets to your baby. :)
