Congratulations! You're the proud owner of a puppy. It's important to take steps now to ensure great puppy health. Louise Murray, DVM, director of the ASPCA's Bergh Memorial Animal Hospital in New York City and author of Vet Confidential (Ballantine, 2008), offers these pointers for your puppy's first year.
Talk to friends to find a veterinarian you can trust. Within a week of bringing your puppy home, take him for a checkup. The doctor will perform a physical and start keeping a detailed medical history.
The overvaccination of pets is currently a hot topic, Murray says. The question is, however, not whether to vaccinate but which vaccines to use and how often. What she calls the 'core vaccines'—those for parvovirus, distemper, adenovirus type 2, and rabies—are essential. 'These shots protect your dog from diseases that are very real, very common, and very dangerous,' she says. Additional vaccines may be necessary based on where you live, where you take your dog, and whether you travel.
Choose a reputable brand of dog food and discuss your choice with your veterinarian. In his first year, your puppy will be on food that is specifically geared toward younger dogs and will likely eat three times a day rather than once or twice.
An excellent measure against pet overpopulation, this procedure ideally should be performed between ages 4 and 5 months, which is before a female dog goes into her first heat and before a male enters puberty. A female dog who is spayed before going into heat is 2,000 times less likely to get breast cancer, Murray says. Males who are neutered before entering puberty have fewer behavioral issues, such as aggression toward other dogs and urine marking.
Puppy Health: Flea, Tick, and Heartworm Medicines
Most dogs should be on medicine year-round to prevent heartworm, a life-threatening parasitic infestation, Murray says. Fleas, often seen as just an annoyance, can actually cause severe skin problems and even anemia. Ticks carry multiple diseases (including Lyme disease and Rocky Mountain Spotted Fever). Your veterinarian can prescribe effective preventives for these two problems.
We’re not talking about the “Sit. Shake.” kind of shake. Nor the fun way they shake off water starting from their nose all the way to the end of their tail. (FYI, dogs can shake off 70% of the water on their fur in just four seconds!)
No, we’re talking about that full-body trembling you’ve likely seen your pooch do from time to time. Why do they do it? And is it something you should be worried about? Let’s shake a leg and find out.
A majority of dog owners in an IAMS™ survey* (64%) think dogs shake because they’re cold. Other top responses were because they’re scared (57%) or anxious (54%).
High-fives all around because it turns out there are a number of reasons dogs shake, and all those are possible correct answers.

Just like their owners, dogs will often shiver when cold.
Opens a new windowDr. Tammie King, Applied Behavior Technical Leader at Waltham Petcare Science Institute, says: “Dogs shiver in response to falling temperatures. Dogs with short or no hair are especially susceptible. You should get them warm, put coats on them or bring them inside.” Same goes for you.

“Shaking is a response to epinephrine or adrenaline secretion — a sign of anxiety where the dog is on high alert,” says

You may notice this when you’re at the vet or there’s a situation where they feel threatened. Dr. Serpell also offers a way to help in some cases: “Identify what’s triggering the behavior. Provide them comfort. Going forward, you can gradually desensitize your pet to the thing it’s afraid of.” Unless it’s clowns. Those are always scary.
Trembling can also be a sign of serious issues like injury, poisoning or kidney disease. Opens a new windowDr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager, Global Science Advocacy at Waltham Petcare Science Institute urges pet owners to be vigilant: “If a pet is unwell in another way, they could be trembling.” If their shaking is accompanied by symptoms like diarrhea, limping or vomiting, you should consult your vet straight away.
