Dog Adjustment Period
Your new dog does not know that you are its new home. All it knows is that once again it is in a different environment, with different smells, different noises, different people who treat it in different way, including giving it different commands and allowing different behaviors, feed it differently and maybe have other animals or children for it to adjust to. Your dog needs TIME to do just that, adjust to everything new in its live. All these new things and your expectations are going to cause your dog some initial stress until it adjusts to its new life.
There are three things that will ensure your success as you take on your housebreaking challenge, and I can’t stress the importance of them enough:
Crate training uses a dog's natural instincts as a den animal. A wild dog's den is his home, a place to sleep, hide from danger, and raise a family. The crate becomes your dog's den, an ideal spot to snooze or take refuge during a thunderstorm.
The primary use for a crate is housetraining. Dogs don't like to soil their dens.
The crate can limit access to the rest of the house while he learns other rules, like not to chew on furniture.
Crates are a safe way to transport your dog in the car.
Dog to Dog Introduction
Bringing a new dog into a home with current dogs- Adding another dog to your household can bring you and your current dog more fun and companionship. However, it’s important to realize that your current dog, might feel similar to how you might feel if your parents picked your friends and then told you to share your toys with them. In the long run, things will probably work out fabulously, but in the beginning it’s a very smart idea to take a few extra steps to make everyone feel good about the new arrangement. This article provides some guidelines for making smooth and safe introductions and ensuring that your dogs’ relationship gets off to a great start.
Introducing your dog to other dogs in general- While a friendly and social dog may have no problem meeting another dog face-to-face while on a walk or at the dog park, dogs who are not as friendly and/or socialized need a little extra assistance to make sure a good "first impression" is made. Much like people, first impressions with dogs are also very important.
Dog to Cat Introduction
Dogs and cats can usually live together peacefully, although creating a harmonious "blended family" requires some planning, patience, and careful guidance on your part.
To "titer" or "titering," as in the act of submitting a blood sample to determine whether an animal has enough antibodies to ensure immunity against a particular disease.
Whether the preventive you choose is given as a pill, a spot-on topical medication or as an injection, all approved heartworm medications work by eliminating the immature (larval) stages of the heartworm parasite. This includes the infective heartworm larvae deposited by the mosquito as well as the following larval stage that develops inside the animal. Unfortunately, in as little as 51 days, immature heartworm larvae can molt into an adult stage, which cannot be effectively eliminated by preventives. Because heartworms must be eliminated before they reach this adult stage, it is extremely important that heartworm preventives be administered strictly on schedule (monthly for oral and topical products and every 6 months for the injectable). Administering prevention late can allow immature larvae to molt into the adult stage, which is poorly prevented.
Flea & Tick Medication
The Companion Animal Parasite Council (CAPC) guidelines call for year-round, lifelong prevention of common external parasites, including fleas and ticks. The guidelines recommend using parasite control methods that consider the lifestyle and health of the pet, managing the pet’s environment, and working closely with owners to prevent infestation and protect the health of the entire family. Consult your veterinarian to figure out the best product and plan for your pet and family.
