Can a Portuguese Water Dog Eat Grapes?

Verdict: ❌ NO

Why Grapes Are Dangerous for Portuguese Water Dogs

Regardless of the breed, grapes and raisins are highly toxic to dogs. While the exact toxin was long debated, recent research points to tartaric acid as the cause of toxicity.

Portuguese Water Dogs, despite their athletic nature and hardy constitutions, are just as susceptible to grape poisoning as any other dog. Even a small amount can trigger a severe reaction in some dogs, while others may be more resilient; however, the risk is far too high to ever attempt feeding them.

The Risks: What Happens?

Feeding grapes to your dog can lead to acute kidney failure. This is a medical emergency that can progress rapidly.

Warning Signs of Grape Toxicity:

Vomiting and Diarrhea: Usually occurs within a few hours of ingestion.
Lethargy: Unusual tiredness or weakness.
Loss of Appetite: Refusing favorite treats or meals.
Dehydration: Dry gums or skin.
Decreased Urination: A critical sign that the kidneys are shutting down.

What to Do If Your Dog Ate Grapes

If your Portuguese Water Dog has accidentally ingested a grape or a raisin, time is of the essence. Follow these steps immediately:

Call Your Veterinarian or Pet Poison Control: Do not wait for symptoms to appear. Early intervention is the key to preventing permanent kidney damage.
Do Not Induce Vomiting Unless Instructed: Only induce vomiting if your vet specifically tells you to do so over the phone.
Identify the Amount: Try to determine exactly how many grapes were eaten and how long ago it happened. This helps your vet determine the urgency of the treatment.
Monitor for Symptoms: While on the way to the clinic, keep a close eye on their behavior and breathing.
