Are Miniature Schnauzers Hyper?

To better understand whether miniature schnauzers are hyper it helps to take a closer look into this breed's history and purpose. Of course, as with all dogs, no general rules are written in stone when it come to temperament. You may find some specimens who are more energetic and others who are more on the mellow side.

The injection is the best option for dogs who are actively vomiting and struggle taking anything by mouth as this assures that the dog gets to absorb the full initial dose. 

The general directions and dosage of Cerenia for dogs varies depending on the dog's age and circumstance. 

For instance, in puppies that are 2 to 7 months old, they can be given Cerenia for up to 5 days, while in dogs older than 7 months, it can be given as needed until the vomiting has stopped.

According to Cerenia's Package Insert, Cerenia is given at a minimum dose of 2 mg/kg (0.9 mg/lb) for prevention of acute vomiting; whereas, for prevention of motion sickness for dog 4 months or older it is given at a dosage of 8 mg/kg (3.6 mg/lb) at least two hours before travel. 

Consult with your vet for proper dosing instructions as directions may vary based on individual cases such as age.

Maropitant  (Cerenia) Side Effects in Dogs 

Normally, Cerenia is well tolerated, and even healthy dogs receiving doses up to three time the recommended dose didn't manifest adverse effects. However, as with any drugs, Cerenia can cause side effects in dogs.

Cerenia should be used with caution in puppies who are younger than 4 months because of the potential for bone marrow hypoplasia (decreased blood cell production from the bone marrow). This drug must also be given with caution in dogs suffering from underlying liver problems or heart disease. 

The most common Cerenia side effects in dogs where noted when the drug was given in high dosages. These side effects included drooling, diarrhea, blood in the stools, retching, weakness, appetite loss, tremors and flatulence.

 The injectable form of Cerenia is known for stinging a bit when given, but when the injectable form is kept refrigerated, it should lessen the stinging significantly, explains veterinarian Dr. John.

"A higher frequency of bone marrow hypoplasia (less than normal cells in the bone marrow) was seen in younger dogs taking maropitant. Even in adult dogs it's best to stop dosing after 5 days." Dr. Michael Salkin, veterinarian
