The FDA-approved fluoxetine dosage for dogs is 1 to 2 mg/kg by mouth once a day. With safe rounding, this translates to 5 to 10 mg for a 10-lb. dog, 20 to 40 mg for a 50-lb. dog, and 40 to 80 mg for a 90-lb.
Prozac dosage for dogs

It typically comes in 10 mg or 20 mg tablets, and is dosed at between 0.5 – 0.9 mg per pound each day. That means a ten pound dog might receive a dosage of 5 to 9 mg. Always follow the exact dosage instructions provided by your vet.

However, fluoxetine can be toxic to your pet if ingested in significant quantities. It is important to realize that, even at therapeutic doses, your pet may show signs of fatigue, excitation, nervousness, or loss of appetite.
Overdose. Signs of overdose in dogs and cats resemble those discussed under side effects: lethargy, hyper salivation, agitation. Seizures may occur in dogs that have received a massive overdose. Fluoxetine is well-absorbed orally and signs of overdose may present in 30 to 60 minutes.
And if you`ve been taking Prozac for a while, it takes about 4 to 6 days for your body to get rid of just half of it. For most people, it takes about 1 month for fluoxetine (the main ingredient in Prozac) to be completely eliminated from the body after the final dose.
Fluoxetine is used to treat depression, obsessive-compulsive disorder (bothersome thoughts that won`t go away and the need to perform certain actions over and over), some eating disorders, and panic attacks (sudden, unexpected attacks of extreme fear and worry about these attacks).
Dodman, who has used Prozac on animals for more than 25 years, says dogs given the drug could experience the following side effects: Reduced appetite. Lack of energy. Pruritus (itch).
No one should take more than 80 mg per day. A doctor recommends a specific dosage of Prozac based on: the person`s age. the health issue that Prozac is treating.
Within a short time of eating the tablets (usually 1-2 hours) your dog may start vomiting or become agitated. Often you will notice some changes in your pet`s behaviour – your usually happy dog could suddenly seem quieter than normal or may vocalise (cry or howl) more.
Mild cases are reversible, but severe overdose can cause long term damage or death. Many different drugs can cause poisoning in dogs when they are not given as prescribed. This is especially true of medications that were intended for humans. Veterinarians define medication overdose in dogs as drug poisoning.
Fluoxetine for dogs is administered orally once a day over a long period of time. This medication works slowly, and results may not be seen for 3 to 4 weeks, and often for up to 8 weeks. During this time, testing may be used to evaluate the effectiveness of this medication.
The most common side effects include sleepiness and decreased appetite. Other side effects include vomiting, diarrhea, shaking, restlessness, panting, whining/vocalization, incoordination, hypersalivation, and weight loss. Serious/severe side effects include seizures, aggression, and excessive/persistent vomiting.
Maximum recommended dose is 60 mg/day. A lower or less frequent dose (e.g., 20mg every second day) should be considered in patients with hepatic impairment (see section 5.2), or in patients where concomitant medication has the potential for interaction with fluoxetine (see section 4.5).
Adults—At first, 20 milligrams (mg) once a day in the morning. Your doctor may adjust your dose as needed. If you are taking more than 20 mg per day, you may take the capsule once a day in the morning or 2 times a day (eg, morning and noon). However, the dose is usually not more than 80 mg per day.
The product is marketed as Prozac Weekly. Fluoxetine is indicated for maintaining an antidepressant response after initial acute treatment with fluoxetine 20 mg. Fluoxetine 90 mg is dosed once-weekly. Weekly dosing should be initiated 7 days after the last daily dose of fluoxetine 20 mg.
Fluoxetine overdose typically results in a benign clinical course, with the most common symptoms being tachycardia, drowsiness, tremor, nausea, and vomiting, and has therefore been identified as “minimally toxic in doses up to 1,500 mg and with combined plasma levels [fluoxetine plus norfluoxetine] up to 1390 ng/mL.”1
Prozac and weight gain might be connected to increased appetite. People taking Prozac may feel hungrier than usual and crave certain foods more often. This could lead them to eat more calories than they usually would, resulting in gradual but steady weight gain over time.
You can feel drowsy in the first few days of taking fluoxetine. However, it should get better after the first week or two. You may become more anxious, or it may make you irritable. This should settle after a couple of weeks.
Loss of Appetite – this is one of the more common side effects for dogs on Prozac. If your dog`s lack of interest in dinner coincides with starting Prozac, it may be throwing off their eating habits.
You can take fluoxetine at any time, but it`s best to stick to the same time every day. If you have trouble sleeping, try taking it in the morning.
Common side effects of Prozac include: vomiting, loss of appetite, (uncommonly) aggressive behavior, seizures, itching, and/or diarrhea in dogs. It may also cause damage to the liver and insomnia in your pet. It`s important to pay attention to how your pet is reacting to Prozac.
Doctors may start with low dosages of fluoxetine and gradually increase the dose. Those using the drug must be patient, as it may take 4 to 5 weeks before they see benefits. Increasing the fluoxetine dosage too much or too quickly could potentially be harmful.
Headache, nausea, diarrhea, dry mouth, increased sweating, feeling nervous, restless, fatigue, or having trouble sleeping (insomnia). These will often improve over the first week or two as you continue to take the medication.

Q. How do I get my dog to stop chewing on things? I kennel her when I leave for a few hours, but I can’t go to the mailbox without her eating something.
ANSWER : A. If she’s young, then this is just normal puppy behavior. Don’t worry about it. The thing about puppies is, they explore using their mouths. If your puppy grabs a coat hanger, or a slipper, you should roll up a newspaper, and smack yourself on the head with it for leaving those things out.. your puppy is going to explore things, that’s normal! It is 100% up to YOU to keep those things away from your puppy when your puppy is unsupervised… even for just a moment.

Remember to never scold your puppy for grabbing these things. They are just curious little cuties, and they don’t chew things up to bother us.. Dogs do not have intentional thought, so they aren’t ever doing anything ON PURPOSE to us.. The most important thing you can do when your puppy is chewing something you don’t want her to be chewing is TRADE her the inappropriate item with a toy of hers, so she understands “no honey, that isn’t what puppies chew on… THIS is what puppies chew on!” and then begin playing with her using her toy to show her that TOYS ARE FUN.. Way more fun than a boring ol’ coat hanger.

Another helpful thing you can do is have two bags of toys. In each bag is many different kinds of toys. Lots of chew toys, lots of soft squeaky toys, lots of rope-type toys, a bunch of balls.. All kinds of things! For one week you have bag#1’s toys out for your puppy to play with.. At the end of the one week, you collect those toys, and you bring out bag#2! The toys will be more interesting/feel like new to your puppy, which will in-turn, make her chew less inappropriate things. Her toys are too fun to care about that dumb Wii-mote that you left laying around.

Hope this helps!

Q. My Lab puppy just got into my Prozac, they are 20mg capsules. I don’t know how many she ate. What should I do, I cant afford a vet today
ANSWER : A. Call the poison desk straight away to see if your puppy requires immediate treatment or not. You need to have an idea of the number of tablets and the dogs weight.

Q. My puppy is urinating a lot. And the lady I gave one of the puppies to said she thinks her puppy has diabetes could my puppy have it to
ANSWER : A. It is not likely that either one of these puppies has diabetes. It is very uncommon for a puppy that young to have diabetes. If your puppy is straining to urinate or is urinating very small amounts frequently and cannot seem to wait for very long between urination, he may have a urinary tract infection. It is quite possible that your puppy is completely normal. I would suggest an exam with your veterinarian and discuss the behavior with them. They may suggest a urinalysis. Your puppy should be going to the vet at 3 week intervals for vaccinations at this age, so you can discuss it when he has his next set of vaccines. The other person with the other puppy should also be taking hers to a vet for proper immunizations and she should also discuss her concerns with her vet.

Q. My dog should have had her puppies by now. It doesn’t appear to be a false pregnancy to me, however I can’t really tell. Any tips?
ANSWER : A. The standard length of a pregnancy in dogs is about 60-63 days post-breeding. If your dog is nearing that date, it could be that she is having a gestation that is longer than normal. Dogs that are first time mothers can commonly have a longer pregnancy, which may shorten as they have more litters. Signs of an immanent labor include an increase in nesting behavior, discomfort such as pacing or laying funny, “waxing” of the nipples where a waxy pre-milk substance (called colostrum and important in puppy immune function) appearing, or visible contractions rippling along the side of the abdomen (more visible in short-haired dogs).

If you are concerned about the puppies being stuck or the wrong size, you can have your local vet take an X-ray of your female. This is typically done by vets involved in breeding (called theriogenologists) and is used to determine how big the puppies are and how many to expect. Knowing this information is great for making sure there are not puppies stuck in the birth canal, and for knowing if they are premature or not. The X-ray may also show if no puppies are present, which can confirm a phantom pregnancy.

Q. My puppy ate 2 peanut butter with chocolate chip granola bars.
ANSWER : A. It is important to know your pup’s weight, age, and breed. It takes a decent amount of milk chocolate to cause any issues in a dog. However, if it was dark chocolate, and your dog is very small (2lb small breed) then you should consider going to the vet. If your dog is a little larger, I wouldn’t worry about it too much. Keep a very close eye on your puppy for the next couple of days, and check each bowel movement.

I am hoping you didn’t scold your dog for eating the granola bars. I say this because you may have, when truly, it was your own fault. Allowing your puppy to get into trouble like that is irresponsible. A puppy should be crate trained, and crated when unsupervised. Not only that, but if your puppy had already eaten the granola bars, scolding is pointless. Scolding after the fact is always pointless. If you’re going to scold, or redirect your puppy, you should do is DURING the act, and not after. The puppy will only learn that you are scary, and unpredictable if you scold after he has done something bad and forgotten about it.

Q. From whom should I get my puppy? The local shelter, my neighbor, a breeder, or a pet supply store?
ANSWER : A. Many people believe that it is better to get a puppy from a reliable breeder. While there are benefits to this, there are benefits to some of the other available options as well. A reliable breeder will introduce you to the puppy’s mother and will allow you to see the environment in which the mother and her puppies live. Often, breeders will also supply background genetic and familial information, so you will know what to expect for your puppy’s future health and temperament. The same can be true for a well-known neighbor with whom you are friendly and familiar with his or her dog.

Alternatively, you can find a puppy in need of a warm and stable home at your local shelter. Here, the benefit is in knowing that you are supporting a worthy service, as you save the life of a dog that would not have had a chance without you.

Q. What solid food should I start 4 week old Pit Bull puppies on?
ANSWER : A. A puppy food designed for large breed puppies can help with rapidly growing bones and joints and can be given in a wet form easily to puppies learning to eat solids. You can also provide a dry kibble for them to try and should moisten it with water or some formula to make it easier for the puppies to eat and digest. As the puppies grow and their teeth come in, they will begin to eat and explore more of the solid food on their own.

Mom should also be on a Puppy formula while nursing her puppies as it will provide extra nutrients to both her and babies while they are in a very rapid stage of growth!

Q. I just got a female Pug she is only 4 weeks old due to someone stole he mom while she was outside. I am giving puppy replacement milk please any advi?
ANSWER : A. Oh what a sad story. It is good that you are feeding a puppy replacement milk, follow the instructions on the package for amounts at corresponding age. Keep an eye on its weight too preferably daily and if it isn’t putting on weight or seems unwell have it checked by your vet. You can start introducing a puppy food in the next week or so and by 8 weeks it should be totally weaned onto puppy food. It will need vet check soon and start it’s vaccines at 6-8 weeks depending on the vaccine your vet uses.
