Your puppy’s nutritional needs will change as he grows into adulthood, but how do you know when your puppy is ready for adult food?
Depending on his breed size, at some point between 12 and 24 months of age, you should reexamine your puppy's nutritional needs and choose the right adult formula. His adult food could depend upon his metabolism (Does he gain weight easily?) and his activity level (Is it low, normal, or high?) These factors can help you find the ideal food for your dog.
The transition to a premium adult formula should begin when your dog approaches adult height and weight. The kind of dog you have will determine the right time to switch. When you do switch to adult formula, follow the same four-day process as you did when introducing your puppy to premium puppy food.
Small-breed dogs tend to mature physically much sooner than large-breed dogs. Follow these guidelines to help you decide when to switch formulas:
As your new puppy quickly matures into adulthood, he needs nutrition appropriate for his 'new' body. That means a high-quality, premium adult formula. Most veterinarians agree that feeding a complete and balanced premium food, such as IAMS™ ProActive Health™ Adult MiniChunks, throughout your dog's adulthood can promote a long and healthy life.
You’ve likely heard your dog let loose his inner wolf and belt out a few long howls. 73% of dog owners in a recent IAMS poll* believe they do this to communicate. This form of vocalization has a long history and is used for different reasons. Understanding more about howling will help you understand your pooch better.
Howling is an ancient trait wolves use to communicate with other members of their pack and other packs over long distances. They may be trying to locate a lost member, show off the size of their pack or warn of danger. It’s like a canine group text.
A wolf’s howl can be heard up to 10 miles away.
Each wolf has their own unique howl, so pack members know who they are, even miles apart.
Dogs instinctually respond to howling-like noises by howling themselves. Sounds such as sirens, other dogs, singing or your kid learning the violin is usually enough to get them to sound off.
Dogs are still very social animals; it’s just that now we’re their pack. When they miss us, they’ll howl in hopes we respond.
Opens a new windowDr. James Serpell, BSc, PhD, Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine, explains it this way: “That [howling] is an attempt on the part of the dog to ask the owner basically, ‘Where are you so that I can rejoin you?’”
Dr. James Serpell doesn’t believe so. “My own research has shown that it is common across breeds. People think huskies may be more prone to group howling.”
Dogs going through separation anxiety may howl excessively when left home alone. Dr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager for Global Science Advocacy at Waltham Petcare Science Institute, says, “If you reinforce quiet behavior, they are less likely to continue howling.” You can do this by quieting your dog and then leaving for a very brief time before returning and rewarding them when they stay quiet. Gradually increase the time you’re gone to reassure them you’ll always be back.
