Lysol is a Phenol toxin. It seems unlikely to cause much of a problem, but it will depend how much she ate. It would be best to see a vet to get some activated charcoal (only available through a vet). good luck! <br /> <br />Disease description in this species: <br />A case of mild phenol toxicity resulting from percutaneous absorption in a dog was reported. Transient clinical signs included anorexia, excessive salivation, and muscular twitching. Following treatment, skin lesions persisted for about 7 days. 2 <br /> <br />Another case report described immediate anxiety, blood tinged hypersalivation, tremors, and panting in 3 dogs that received 90-97 mg/kg PO of a phenol solution. On examination all dogs had severe oral ulcerations. Endoscopic examination and biopsies yielded a diagnosis of gastric mucosal necrosis in two of the dogs. Hematological abnormalities included neutropenia,toxic neutrophils, thrombocytopenia, and increased muscle enzymes. All dogs recovered uneventfully with supportive treatment (see treatment section) and were asymptomatic within 1-2 weeks, although one had to have short-term nutritional support via a percutaneous endoscopically placed gastrotomy (PEG) tube. 4 <br /> <br />IMMEDIATE TREATMENT UPON INGESTION <br />1) Assess the damage to visible mucous membranes. <br /> <br />2) Administer milk or egg whites to delay gastrointestinal absorption of the compound. In general, emetics are contraindicated because of phenol's caustic nature. <br /> <br />3) Use gastric levage if esophageal injury is not suspected. followed by repeated gastric lavage. Maintain a patent airway with intubation and control respiration. Activated charcoal can be used as an adsorbent, 1 g/5 ml water, 10 ml slurry/kg PO. Follow the charcoal with milk or egg whites to help to protect the injured mucous membranes from more damage. <br /> <br />4) Fluid therapy is indicated since phenolic compounds are eliminated via the urine. <br /> <br />5) Use gastrointestinal protectants as outlined below.

Hi againCustomer

I have been away from the computer all day, just logged on and saw your question now.
I wanted to add a bit to the previous answer... just to help you further.

First, I wanted to mention that although some Lysol formulations contains phenols, not all of them do. Please read the label carefully to see what the active ingredients are. Alternatively, tell me what type of Lysol you have (what scent and whether it is in a spritzer or aerosol) and I can look it up. Any ingredient that has the word PHENOL in it would be a phenol, as Dr.Dan stated.

Here is more information:

Secondly, I wanted to mention that IF this contained phenols, it can be very serious. It can lead to SEVERE oral and gastric ulceration, to the point that dogs have to have a feeding tube placed in the stomach surgically in order to by-pass the mouth and esophagus because they can be so damaged.


Right now I would like you to give your dog a mix of 50:50 water and milk - 1/2 cup NOW and then 2 tablespoons every 15 minutes.

You need to get your dog to the vet ASAP to get some sucralfate which is a stomach protector. This can be given in pill or milkshake form and will help to protect the stomach and intestines. I understand you have financial concerns and will list some places to turn for loans/aid at the bottom of this post.

When you get the dog to the vet, he will do a complete oral exam looking for burns. However, pain, inflammation, redness and swelling may not be visible for 2-4 hours after the phenol was eaten. The full extent of the injury won't be known for 12 hours after exposure as the corrosive burns take that long to show up.

Treatment of burns in the mucosa should include antibiotics, pain medication as needed, gastrointestinal protectants (e.g. sucralfate), anti-inflammatories (corticosteroid use is controversial) and general supportive care.

In cases with severe oral burns or esophageal burns, your veterinarian may have to place a feeding tube into the dog's stomach so that food and water can be given to her through this tube while the mucosa heals. This can take weeks. There is a risk of a stricture or narrowing forming in the esophagus.

So, in summary, this is a very serious poisoning!! Please continue the milk mixture and get your dog to your vet promptly. Call them to let them know you are coming so they can get ready.

Here is more about phenol poisoning:

I understand you have financial concerns. If there were a home remedy for this, I would certainly suggest it! I can give you some suggestions for where to turn for financial aid. I'd start with the local animal shelters to see if they know of any low cost or subsidized vet care in your area.

Nationally here are some groups that might help you afford the vet bills:

American Animal Hospital Association
" Through the AAHA Helping Pets Fund, veterinary care is possible for sick or injured pets even if they have been abandoned or if their owner is experiencing financial hardship."

Angels 4 Animals
"Our services range from financial aid to complete treatment
to those pets and pet owners in need."

Care Credit
A credit card company for health care, including veterinary care.
"With a comprehensive range of plan options, for
treatment or procedure fees from $1 to over $25,000, we offer a plan
and a low monthly payment to fit comfortably into almost every

God's Creatures Ministry
"This fund helps pay for veterinarian bills for those who need help."

"Our efforts focus on serving the elderly, the disabled, and the
working poor."

"We are dedicated to insure that no
companion animal has to be euthanized simply because their caretaker
is financially challenged."

The Pet Fund
"The Pet Fund is a registered 501(c)3 nonprofit association that
provides financial assistance to owners of domestic animals who need
urgent veterinary care."

United Animal Nations
"The m ission of LifeLine is to help homeless or recently rescued
animals suffering from life-threatening conditions that require
specific and immediate emergency veterinary care. We strive to serve
Good Samaritans and rescue groups who take in sick or injured
animals. In certain cases, LifeLine can also assist senior citizens
and low-income families pay for immediate emergency veterinary care."

They also keep a list of local and national help resources here

Of these, the most reliable one in terms of providing assistance is I have heard very good reports about them!

Please let me know how your dog is doing, and certainly let me know if the Lysol did NOT contain phenols. We can then talk about what to do from here. GOOD LUCK!

Good luck, and please let me know what happens!
