While McDonald fries are certainly delicious, they are not meant for dogs. The problem with them is that they are both high in fat and salt, and fatty foods cause pancreatitis in dogs. Pancreatitis is an inflammation of the pancreas, and it's a very serious condition that requires intensive care because it can be fatal. If T'challa ate these fries within the last two hours, you can take him into a vet immediately to have vomiting induced to prevent any problems. If it's been longer than two hours, monitor him. Should you see a loss of appetite, vomiting, and/or belly pain, that could mean he has pancreatitis and you will need to take him into a vet immediately. I would withhold food for tonight and if he appears fine tomorrow and doesn't show any of the symptoms I mentioned above, feed him a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal food. I hope this helps!

We are moving and had Zaxby’s chicken fingers thar are boneless and French fries. Our dog Romeo whose 13 pounds got into our Zaxby’s the moment we left room. He ate some French fries. Should he be ok? We got some Endoscorb that vet gave for his tummy
It may cause a little bit of gastrointestinal upset so monitor for vomiting and diarrhea. You could feed a bland diet of boiled chicken and white rice if he has any gastrointestinal issues but he should be examined by your vet if any clinical signs persist.

My roommate fed my dog some french fries and later he started vomiting.... He vomited everything and he is shivering and looks weak and tired..... Please what do i do now to make things normal?
It could be that he has gastroenteritis (inflammation in his stomach and intestines) from the french fries. I would recommend fasting him for at least the next 12 hours. If he hasn't vomited in that time, you can start introducing small amounts of boiled chicken and plain white rice. If he hold this down, continue this and then start slowly adding in his regular dog food. If he continues vomiting during the fasting period, then I would recommend taking him to a veterinarian for evaluation. Rich, fatty foods can cause a condition called pancreatitis which is very serious and requires treatment by a veterinarian. In the future, I would avoid fatty foods as treats.

My dog ate about a half of a pound of lays barbecue chips. He is a golden doodle and about 40 pounds? will he be ok??
Lays BBQ chips are delicious, but that is a lot of chips for a dog to eat! My first concern would be that Max could get pancreatitis from it. This is a severe inflammation of the pancreas that occurs when a dog eats too much fat, and chips are unfortunately fatty. If he ate them within the past two hours, I would take him into a vet immediately to have vomiting induced to prevent him from getting pancreatitis. If it's been longer than two hours since he ate them, you will have monitor him for signs of pancreatitis. These signs include vomiting, hunched back, painful abdomen, vomiting undigested food, distension of the abdomen, loss of appetite, diarrhea, and lethargy. If you see any of those signs, please take him into a vet immediately. Good luck, I hope this helps and Max ends up ok!

I accidentally left an Arby's burger with mayonnaise, some fries, and fried mozzarella stick out within reach. Maxi ate the stick, burger, and a couple fries. Is there anything I should be concerned about?
Maxi can get pancreatitis from this or diarrhea and vomiting. I would recommend giving her a bland diet (boiled chicken and white rice) just to calm everything down and then monitor her. If she starts vomiting, diarrhea, not eating, becomes lethargic then I recommend bringing her to a veterinarian. I will say the visit may require hospitalization and fluid support if she is dehydrated from everything. Thank you for using Boop by Petco.

My dog got into a small amount of ranch and bbq sauce it was in those small containers from mcdonalds and he possible got a chicken mcnugget too will it harm him in any way
A small amount of these foods should not cause any serious issues. Some dogs may develop diarrhea or an upset stomach from new or different foods. To lessen the chance of this, I would feed him a bland diet (boiled chicken and cooked, white rice in a 1:1 ratio is a good option) for the next day or two! If he does seem to feel bad it is never a wrong idea to visit your vet! I hope this helps!

My dog just puked and I'm worried because a couple days ago he puked after eating his tick medication. This is common after taking his medication at night, which he did. As for today, he had some people food as a treat (French fries, fish). should I
I would be concerned that the vomiting is due to the french fries and fish. French fries would be very fatty for a dog, and if the fish was fried as well, that would be very fatty for him. Dogs should never receive fatty foods, as it predispose them to pancreatitis. Pancreatitis can be fatal, and you may have to rush him into the vet if he keeps vomiting. I will give you a home remedy to try first, however, but keep in mind that if it doesn't help, Sam will have to see a vet right away. In the future, I would never give him any fatty, fried foods again, and would recommend staying away from human food in general. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethar

My dog ate one deep-fried onion ring from Burger King. Should I be worried?
While onions can be bad for dogs that is not likely enough to cause any toxicity problems. However I would be worried about it being fried and causing an upset stomach and pancreatitis. This can be painful and start with a decreased appetite, vomiting, diarrhea and lethargy. If you notice any of these symptoms, take him to the vet for testing and treatments.

Tiny ate a few French fries, he threw up a 2 pieces of it, and later I took him outside like usual, he pooped. Is this normal?
Hello. His poop is a bit soft, but it is too early to be overly concerned. No more fatty or greasy foods, just stick with his regular food & see how he is tomorrow. If he develops any diarrhea or continues to vomit, then please see your veterinarian at your earliest convenience tomorrow. Thanks for using Boop by Petco.

Is it ok to give my dog a small plain hamburger patty (no bun or sauces) from McDonald's every once in a while as a treat? I think a hamburger patty is about 2-3 oz. why or why not? Thanks!
The only problem with that is that the hamburger is fatty, and too much fat in a dog's diet leads to pancreatitis. In my opinion, this wouldn't be a good treat to give Chloe. Instead, how about giving her some boiled white meat chicken (no bones)?? That would be a healthy treat for her to have :-)

My dog a pointer lab mix he's 8 months old. He just ate a small chip bag filled with grease bits from our grill. I don't know what to do.
Hello, sorry to hear about Chase. You can have your veterinarian induce vomiting, however, this may not cause significant clincal signs. He may develop some diarrhea and vomiting as well as a decreased appetite. This is likely due to a dietary indiscretion, however this can also be from hime developing pancreatitis. If you note these signs and they persist for longer the 3-5 days, or if he vomits more than 3 -4 times in one day, or if he develops bloody diarrhea then he should be evaluated immediately. In the interim, you can feed him a bland diet of plain white rice, skinless and boneless boiled chicken, and low fat cottage cheese. Hope this helps and best of luck.
