Hey there! It's sweet that you're thinking of sharing with your pup. Generally, plain, unsalted mashed potatoes are okay for dogs in small amounts. However, be cautious if your mashed potatoes contain add-ins like garlic, onions, or excessive butter and cream. Garlic and onions can be toxic to dogs, potentially leading to a tummy upset or more serious issues like damage to red blood cells.
Here’s what to look out for:
- If your mashed potatoes were simply made (without harmful ingredients), a small amount shouldn't be a problem. Just keep portions modest.
- Watch for signs of garlic or onion poisoning which include lethargy, decreased appetite, pale gums, nausea, vomiting, and diarrhea.
- Other potential symptoms to monitor include a bloated belly or excessive gas if your dog isn't used to this food.
If your pup only had a small taste of a mashed potato mix with potentially harmful ingredients and they seem fine, just keep an eye on them for now. If they show any of the symptoms mentioned above, especially the more severe ones, it's time to reach out to a professional.
If the potatoes contained large amounts of harmful ingredients or your dog is displaying worrying symptoms (like pale gums or not wanting to move), that's when it's considered an emergency, and you should contact a vet right away.
At home, ensure your dog has plenty of water and a quiet space to relax. Monitor them closely over the next few hours.
If you're unsure or your pet’s symptoms worsen, it's best to book a call with a vet on Dial A Vet for professional advice.
