Food allergy is possible, however some issues such as certain parasites (like giardia) can also sometimes require a second round of medication to fully address the issue. Adding in probiotics can also sometimes help with stool as well. Since the diarrhea is back and with blood in it, it would be best to recheck with your vet to see if Bruin needs another round of medication.
I would also bring up potential allergy issues then (4 months is very young to have developed one, but not impossible). If medication isn't helping, your vet can help work on a plan of either an allergy med or a food trial to transition to the new food and see if there is an ingredient triggering it. While it's ideal to be on a large breed puppy food at this age, if there is an allergy, it's better to have that addressed with the right balanced diet that doesn't include that ingredient.

This presentation could be dietary related and as a first approach, I would suggest to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days.
I would definitively recommend a veterinary check up if the signs persist or you notice diarrhoea, vomiting, lethargy or inappetence.

Poor Bruce! If he's acting normal (eating and drinking fine, active and playful, etc.) it's not likely to be parvo or anything else that would be very serious. So you shouldn't need to rush to the ER tonight :)
In a puppy this age, the most likely cause of a small amount of blood in the stool would be some type of intestinal parasites - hookworms, whipworms, coccidia, etc. I would recommend taking a fecal sample to your veterinarian tomorrow morning, if possible - he/she can examine it under the microscope to help diagnose the problem, and will prescribe appropriate medication to treat it depending on what is found.
