Metronidazole Dosage for Dogs

Metronidazole is an antibiotic that is used in dogs and cats to treat various conditions such as inflammatory bowel diseases, unspecified diarrhea disorders, infections caused by giardia, and gum disease.

Metronidazole is given to dogs to help fight bacterial infections in the intestine like giardia. According to the pill guide for medications for your dog and cat, metronidazole can be given to the dog before or after surgery to digestive organs in order to prevent infection.

If your dog has Giardia or Entamoeba infection, give 7 to 14 mg per pound that the dog weighs for five to seven days. For inflammatory bowel disease, the dose is 5 to 7 mg per pound that the dog weighs, given two or three times a day. For anaerobic infections, give 11 to 23 milligrams per pound. Your dog weighs two to four times a day. A dose to prevent infection is left during surgery at the discretion of the vet.

There is a wide range of metronidazole doses for dogs as they take into account many factors that make your veterinarian decide whether to go to a low-end or a high-end end. If it is a medical emergency, the larger dose may be necessary. If the dog also takes other antibiotics, then lower doses will be used. Ideally, the lowest possible dose is used to avoid bad side effects.

Prevent nausea
Metronidazole often irritates the dog’s stomach. If the dog vomits, he also vomits metronidazole. In order to prevent this, the pill guide suggests medications for your dog and cat either to give the medicine with food or shortly after the dog has ingested it for you. Metronidazole can also be converted into combined chewable tablets, which combine medicine and delicious treatment.

Time frame
According to Barbara Fortune, nausea and vomiting in dogs as a result of metronidazole does not occur immediately. Sometimes it may take up to twelve days after giving the first dose to start nausea. This is the time when your dog may start to show signs of an overdose of metronidazole.

Signs of metronidazole overdose in dogs include more common salivation, coordination problems, lack of appetite, strange eye movements, more fatigued than usual, loss of vision, strange twitching and fits. There is currently no test available to warn that your dog has become an overdose.

How long does metronidazole take to work for dogs?
This medication should take effect within 1 to 2 hours, and while effects may not be visibly noticed immediately, but gradual improvements are usually noticeable after a few days.

Does metronidazole make dogs sleepy?
Cases of anorexia, nausea, excessive salivation, gagging, regurgitation and diarrhea are also reported. Harmful effects of metronidazole for dogs and cats normally affect the brain and its equilibrium. Drowsiness, rashes, and incoordination are other side effects.

Can I give my dog metronidazole without food?
Give this medication with food. Because the tablets have a naturally bitter taste, they should not be crushed or chewed as the pet will drool plus likely refuse future doses. After administration, watch the pet closely to ensure the entire dose was consumed. Give medication as directed by your veterinarian.
