Your new puppy's first meals at home are very important. Find out what formula your puppy has been eating, and continue feeding this food for a day or two after you bring him home. If you want to change his diet to a premium food such as IAMS™ ProActive Health™ Smart Puppy Original , gradually move him to the new formula and help avoid intestinal upsets by using the following steps:
Day 1: Fill your dog's bowl with 75% of his old food and 25% of IAMS ProActive Health Smart Puppy Original.
Day 2: Mix his former food and IAMS ProActive Health Smart Puppy Original in a 50/50 ratio.
Day 3: Feed your dog a mixture that's 75% IAMS ProActive Health Smart Puppy Original and 25% former food.
Day 4: Feed 100% of IAMS ProActive Health Smart Puppy Original.
To feed a puppy from weaning to 4 months of age, offer a 100% complete and balanced premium puppy formula. To determine each serving size, start with the daily amount recommended by the feeding guidelines on the pet food label, and divide that number by the number of times a day (usually three times) you plan to feed your puppy.
Serve the food at room temperature and remove the bowl within 30 minutes after he's done eating. After four months, you can feed a puppy twice daily on a regular schedule.
Don't add nutritional supplements to your dog's diet. Adding commercial dietary supplements or 'people food' such as hamburger, eggs, cottage cheese, or cow's milk is unnecessary and might even do more harm than good.
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.
