My dog ate homemade lasagna. What symptoms should I watch for?

Updated On September 23rd, 2025

Pet's info: Dog | Labrador Retriever | Male | neutered | 8 years and 3 months old | 70 lbs

My 70lb lab go ahold of 1/2 a pan of homemade lasagna with homemade sauce off the stove. It's been about 4 hours ago. What should I be watching for and concerned about? So far he appears to be acting normal. The pan was an 8×10 pan about 1/2 full

I smiled when reading this because it's so like a lab to eat half a lasagna! One of my concerns about it is if there are any onions or garlic in the homemade sauce, both of which are toxic to dogs. If there was enough of either, that could cause anemia in Benjamin, signs of which include lethargy, exercise intolerance, decreased appetite, and pale gums. The other concern is the fattiness of the dish. Too much fat causes pancreatitis in dogs. Signs of that include vomiting, abdominal pain, vomiting undigested food, anorexia, hunched back, diarrhea, loss of appetite, and lethargy. If you see any of those signs, take him into a vet immediately. I hope this helps!
