We know how stressful adjusting to a new home can be – not just for your two-legged family members, but for your four-legged ones, too! Help make your pets feel a little more at home in your new place with these helpful tips.

  1. Pet proof your house. Did you know that certain plants and food can be toxic to pets? Common household items like cleaning products and medications can also pose a threat. Especially in a new environment, curious pets can get into household hazards. Be sure to store these in areas that are inaccessible to your furry friends.

  2. Make sure your pet has proper identification. In addition to standard collars that may come off or get lost, consider getting your pets microchipped. The permanent ID option is as easy and as painless as a vaccination, and greatly increases your chances of reuniting with a lost pet. If Fido is already microchipped, be sure to update the microchip database with your new address information.

  3. Keep your schedule consistent. Pets are creatures of habit, so maintaining your regular routine will help to make things feel a little more normal. Sticking to your usual times for walks, meals, cuddle time and bed time can help your best friend adjust.

  4. Be loving and patient. The best way to make pets feel comfortable in a new home is to associate positive experiences with it. Remember to be patient with them and give them lots of affection and treats, and you will have plenty of new, happy memories in no time. You can also take advantage of calming pet products like pheromone diffusers and collars, thundershirts and composure treats to help Fluffy feel at ease.

  5. Get to know your veterinarian. Bringing your pets to the veterinarian for a routine exam is the smartest and easiest way to keep them healthy. Call us at (978) 453-1784 so we can schedule a visit to get to know you and your pets!

Hill’s Pet Nutrition recently put out a voluntary recall on their canned food products due to potentially elevated levels of vitamin D. Although animals benefit from vitamin D, ingesting too much of it can lead to potential health issues. Luckily, in most cases, complete recovery is expected after discontinuation of the canned food.

Hill’s is working in coordination with the US Food and Drug Administration (FDA) to get the affected products recalled. As of right now, the recall only extends to canned food and does not apply to dry food, cat food, or other treats.

Dr. Carol Cookingham, DVM

It is with both great excitement and sadness that we announce the retirement of Dr. Carol Cookingham from Linwood Animal Hospital.

Dr. Cookingham has been an esteemed member of the Linwood Animal Hospital family since 1981.

VaccineCBS Boston reported that, about three weeks ago, Massachusetts confirmed its first case of dog flu this year. Veterinarians estimate the vaccine is about 60% effective and they are urging in-state dog owners to vaccinate their pets for added protection.

The American Kennel Club describes dog flu as ‘an infectious respiratory disease caused by an influenza A virus, similar to the viral strains that cause influenza in people.’ The disease is airborne and respiratory secretions can be spread via coughing, barking, and sneezing. It can also be transmitted via infected objects, such as toys, bowls, and collars.

Dog flu typically incubates for two to four days. After day four, viral shedding starts to decrease but dogs can remain contagious for 10 – 26 days, depending on the specific strain of dog flu they contracted. If a dog comes into contact with dog flu, (s)he will almost always be infected.

Common symptoms of dog flu include:

The doctors and staff at Linwood Animal Hospital are excited to announce that our renovations are complete! We have an all new reception desk, exam rooms, flooring, and waiting room - including a cat-only waiting area. 

We look forward to providing our loyal clients with a more comfortable experience in our new facility, while also allowing our veterinarians and staff to provide more services and better care to our patients. 

There is a new tick-borne illness on the rise. The Powassan Virus (or POW) is a rare but very serious disease found in New England and the Great Lakes region of the United States. The POW virus is spread by the bite of an infected deer tick, the same tick responsible for the spread of Lyme disease.

Flea/tick prevention productsThere is no known test for the virus in animals. It is also unknown at this time if the disease affects pets as it does humans. Symptoms of this disease in humans may present itself as fever, vomiting, weakness, confusion, loss of coordination and seizures. This is why  prevention is so important – not only for your pets, but for you and your family as well! Remember that ticks can also hitch a ride in on your pets from the outdoors.

Call us at (978) 453-1784 if you have any questions or if you need help choosing the right tick prevention product for your pet.

dog tick diagramIt's such a treat when we get a warm winter here in New England, but unfortunately, ticks love it too! Without heavy snow cover, and the spring weather approaching, ticks are multiplying at an alarming rate.

Ticks can spread serious infectious diseases such as Lyme, Rocky Mountain spotted fever, Anaplasmosis, Ehrlichiosis and Babesiosis, to pets and people. This season, be sure to protect your pets from these little monsters! The health of your pets and family depends on it. Learn more about the rise of ticks in New England here.

At Linwood Animal Hospital, we carry and recommend Vectra 3D for dogs and Frontline for cats. Both are flea/tick preventative topical oils which you apply to your pet once a month. We also carry Bravecto, an oral preventative for dogs which protects them for up to three months.

Pet insurance can help you manage the cost of caring for your pet should the unexpected happen. Here at Linwood Animal Hospital we strongly encourage you to consider health insurance for your pet.

Why Do I Need Pet Insurance?

No one likes to think about their beloved pet getting hurt or sick, but it can happen at any time. Pets are typically curious, active and often quite fearless, so it's difficult to protect them from all dangers all the time. Pets also get sick, just like we do. In fact, every year about 6 million dogs and cats are diagnosed with cancer in the United States.

Pet Health Insurance FAQsFortunately, there are more life-saving treatments available for pets than ever before. However, with these new advances, come more expenses. That's where pet insurance comes in. By covering your pet, you can make sure you will be able to afford the medical care he or she needs.

How Does Pet Insurance Work?

  • Get Treatment
  • File a Claim
  • Get Reimbursed

With pet insurance, you can visit any veterinarian or emergency hospital. You pay your bill at the time of service and submit a claim to the pet insurance company, which reimburses you directly with a check.

Some insurance companies even have the ability to make a direct deposit straight into your bank account, or submit payment directly to the veterinary hospital.
