Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about E. Low blood pressure is the most common sign of toxicity. Other signs include lethargy, excess salivation, increased heart rate, vomiting, diarrhea, weakness, and cough. If you see any of those signs, rush him into a vet immediately. I hope this helps!

    He will be just fine. He still received a proper dosage for a dog his size by getting 20mg at a time. You can still go forward wtih his regular schedule here moving forward. Thanks for visiting Petco Pet Education Center, formerly Petcoach. Take care. : )

    Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. A single dose of this enalapril to your 110 lb dog will likely be OK, and you should not have to bring him to your veterinarian. Please monitor for any vomiting, diarrhea or weakness, and absolutely have him/her seen by a veterinarian if you notice any of these signs. I hope this is helpful!

dog (5kls) accidentally ate my other dog's enalapril (.25mg).what should i look out for? he's 2 yrs old with no heart condition at all.
The dose for dogs is 0.5mg per kg. Enalapril comes in 2.5mg tablets so did Charlie eat 2.5mg or 0.25mg? If he only at 0.25mg he probably will have no ill effects. If he ate 2.5mg then he could have some side effects. Things to watch out for: low blood pressure, increased urination, decreased appetite, vomiting, sudden lethargy or weakness.

My healthy dog (~35lb) may have ingested my older dog’s (~38lb) enalapril maleate (10mg) and spironolactone (12.5 mg)
A single dose (not overdosed) should not cause any harm if your dog is fit and healthy. Monitor him for the day, he may feel weaker than normal and urinate more. Make sure water is available all the time.

I dropped a 5 mg enalapril on the floor at 12:00PM today and my dog ate it before I could stop him. It is now 5:30PM and he has been fine all day, should I be concerned?
Hello. 5 mg was a very small dose of enalapril ( which we do use regularly in dogs ) for a dog that weighs 55 pounds. Abby will be perfectly fine & you have nothing to worry about. Thanks for using Boop by Petco.

My mom’s blood pressure medicine (Lisinopril 10mg) spilled and my 13lb pup ate one pill. Do I need to be worried or take her to see a vet?
Hi, Lisinopril is used in the treatment of both heart failure and hypertension (high blood pressure) in dogs. In dogs required the drug the safe dose is 0.5 mg/kg which in the case of 13 lb (6.5 kg) puppy that would be 3.25mg which makes 10mg an overdose. Overdose may cause lethargy, increased heart rate, vomiting, and hypotension (low blood pressure). Seek veterinary care immediately. If it has happened less than an hour ago the vet may be able to induce vomiting. If not he will need to be monitored and supportive care depending on signs.

Not sure, but my 1 year old cocker spaniel May have eaten 1 of my 30 mg lisinopril. He seems fine. Should I be concerned?
He should be fine. You may see some vomiting, diarrhea and/or lethargy. He would need to ingest 8 of the pills for there to be a risk of toxicity. If necessary, withhold food for 24 hours, allowing small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts until any symptoms of GI upset resolve. Transition slowly to his regular diet afterwards. If symptoms persist or worsen, have him examined by your veterinarian.

gave my dog his 2nd dose of enalapril less than 12hrs of his first dose.should i worry?
I would not be overly concerned however, it depends on the dose and how far apart the doses were given. If you are talking about 2 hours apart then there could be an issue. If you are talking more like 9-10 hours apart then it should be just fine.

My 5 month old 25lb puppy ate a 50mg proin pill meant for my other dog. Is he gonna die?
Havoc should be absolutely fine after ingesting the Proin tablet! He ingested approximately 4.4 mg/kg (milligrams per kilogram of body weight), and more serious signs of toxicity usually occur with doses over 15 mg/kg. There is a chance that Havoc may experience agitation, vomiting, decreased heart rate or elevated blood pressure. While these signs generally resolve within 24 hours of ingestion, it would be ideal to take Havoc to his vet for an exam and blood pressure measurement. I hope this helps!

My vet said to stop enalapril cold since his kidney and liver levels were high on his bloodwork. He has also lost interest in eating, is drinking more water than usual, and is vomiting occasionally. Is this advisable to stop a medication cold?
Thanks for using Boop by Petco! If that medication is causing side effects then the short answer is yes. Enalapril can affect the kidney values and cause a dog to not eat so your veterinarian is stopping that medication probably to try to get Binx to eat better. Your veterinarian knows his medical history well so they would know well if this was a good decision but that is likely the rationale. I really hope that your boy starts feeling better soon. Good luck!

My 6 lb yorkie ate 5 mg Benazepril that was intended for my bison who is 25 pounds. Will that hurt her?
Hi there and thank you for using Boop by Petco to address your concern. At the high end of the dose range for Benazepril, Maui's dose would be about 13.6mg so she has not had a toxic dose. You may see symptoms such as vomiting, diarrhea, lethargy, weakness, etc. If you see these symptoms, I would get her in to be seen by a veterinarian as soon as possible. Otherwise, just keep monitoring her for the time being. I hope this helps guide you in the right direction. Please let me know if you have any other questions.

If my dog ate a carvedilol pill how long would it take for a symptom to show?
Thank you for contacting Boop by Petco with your question about Kitty. If you think she ate a carvedilol pill, you need to get her into a vet immediately. It can take a few hours to see signs, but it can cause severe drops in blood pressure that can be life-threatening. Please take her into a vet immediately. Best of luck.
