About Your Lab's Health
When a lab first comes into Lab Rescue care, we send them to one of our vets for an initial checkup. Our vet clinics perform an overall wellness exam and perform the key blood tests that tell us whether the lab has any pre-existing conditions like Lyme Disease or Heartworms. We begin initial treatment if it is required.
When you adopt your lab you may have medications to administer. It is important that you continue giving medications if they have been provided.
The Lab Rescue contract includes a clause that you must take your lab to your own veterinarian within one week of adopting him or her. We include that clause so that:
a) your vet begins to know your lab as soon as possible
b) your vet can perform their own examination and confirm the wellness of the dog
Lab Rescue takes in a lot of dogs that are Heartworm (HW) positive. This condition is easily prevented if you give your lab a once a month yummy heartworm preventative like Interceptor or Heartguard. Giving your lab their monthly heartworm prevention is one of the contractual obligations of adopting from Lab Rescue.
If you adopt a lab that is already heartworm positive, that dog will need to receive a vet administered treatment. Heartworms can be successfully treated with no ill effect to your lab's long term prognosis or quality of life. You should not be afraid to adopt a heartworm positive dog but you will need to understand the treatment protocol and follow the directions of your veterinarian to the letter.
Heartworm Treatment Overview
Heartworm positive dogs will be placed on an Ivermectin based heartworm prevention (Heartguard / Triheart) for 3 months prior to treatment kill the juvenile heartworms. Dogs will get the first preventative at the time of diagnosis and will normally be given at the vet’s office and two additional preventatives to be given over the next two months.
Heartworm positive dogs will be given Doxycycline for 30 days. Recent studies have shown that treatment of heartworm positive dogs with an antibiotic (specifically, doxycycline) can decrease the inflammatory reactions from dying worms during treatment. Studies have also shown that doxycycline treatment prevents adult heartworms from reproducing, decreases their body size, and decreases the ability of early larval stages to develop into later larval stages. This again, decreases the total amount of worm volume within an infected dog. Less worm volume can decrease the amount of inflammation in the body when these worms are killed by medical treatment.
The treatment of the adult heartworm is required in all cases. Adult heartworm treatment should be initiated 3 months after diagnosis (and thus the dog will have been on heartworm prevention for 3 months. Treatment of Heartworm is accomplished by giving injections of Immiticide which is currently the only approved medicine to kill the Heartworms.
Non-symptomatic dogs (most dogs that are diagnosed with Heartworms). Dogs will go to one of our vets for treatment They will be given 2 shots of Immiticide 24 hours apart and go home on the 3rd day.
Symptomatic and older dogs will receive a split treatment and will go to one of our vets for treatment They will be given 1 shots of Immiticide and observed for 24 hours this is followed by a 30 day rest period then they will be returned to the vet and will be given 2 shots of Immiticide 24 hours apart and go home on the 3rd day.
The protocol for treatment of Heartworms will be decided by the Veterinarian doing the treatment and may vary somewhat from the above.
NOTE: Once the adult heartworm treatment has been started it is VERY IMPORTANT that these dogs be STRICTLY confined. This means: NO RUNNING, JUMPING, PLAYING. CRATE CONFINEMENT IS IDEAL NO WALKS LONGER THAN 5 MINUTES (ideally they do their business and then go back in the crate). These strict restrictions are necessary for 1 month following the final adult heartworm treatment.
Following these restrictions, gradual return to normal exercise is recommended (over several weeks).
The injections of the adult heartworm treatment can be painful, so if necessary some dogs are placed on pain medications for a few days after the injection(s).
Other side effects of worm die-off include pneumonitis (lung tissue inflammation) and thrombi ernbollsm (throwing clots to the lungs or other tissues).
Clinical signs to look out for are: lethargy, decreased appetite, cough, exercise intolerance.
NOTE: If ANY of these signs are noted the dog needs to be seen by a veterinarian for evaluation.
We can minimize these effects with strict confinement following the adult heartworm treatment.

First Aid and Ongoing Health Issues
Your relationship with your vet is key. At any time you may find that your lab starts to experience a health problem or injures itself. Many Lab Rescue volunteers and lab owners maintain a first aid kit for the small things that occur from time to time. We use this first aid kit as a temporary measure until you can take your lab to your vet.

Remember: call your vet or, if after hours, take your lab to the closest emergency clinic for acute problems.
