My dog pooped out jelly like blood(?) in his stool this morning. Almost seemed like he had some type of fatty substances in it. I recently changed his food. He seems fine, he ate this morning as well. He doesn’t seem different. Should I seek vet help?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It sounds to me like there was mucous in the stool along with the blood. This can be seen with diarrhea and if the blood was a small amount, I would not be too concerned by this, especially if he recently was switched to a different food. I would recommend feeding a bland diet as outlined below and then transitioning back to the new dog food over a 7 day period. If the problem continues or starts back up after reintroducing the new dog food after the bland diet, I would recommend feeding a different dog food altogether. If there is still no improvement, I would recommend having a veterinarian examine Tito so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further!
