Artificial Insemination & Reproductive Services:
Promoting Healthy Litters

veterinary artificial insemination

If you are ready to breed your canine, our veterinarians will be happy to assist you. We are experienced in providing a wide range of veterinary reproductive services and will do everything possible to ensure your dog produces a healthy litter of puppies.


Fertility Evaluations

Ensuring that your dog is in good health and at optimal fertility is essential for achieving a successful pregnancy. Following are ways our veterinarians can help.

For a male dog, we will collect and evaluate a sample of his semen to determine the quantity and quality of sperm present. This way, when a window of fertility opens, you’ll be sure that you’re making the most of the opportunity.

In the case of a female dog, we will conduct hormone assays of progesterone to identify when ovulation has occurred and whether it’s the most fertile period for your dog to breed.

Canine Artificial Insemination

Should you choose to breed your dog via artificial insemination, our veterinarians are skilled at performing this procedure using fresh chilled or frozen semen. When fresh chilled semen is provided, it is typically inserted vaginally. Frozen semen is implanted surgically in order to optimize fertilization.

Dog Pregnancy Evaluations and Monitoring

Approximately 26–30 days after artificial insemination has taken place, our veterinarians will verify via an abdominal ultrasound that your dog is pregnant. In addition, we will examine the pups to confirm that they are developing properly.

When the time comes for delivery, our veterinarians are experienced in performing caesarian sections, should it be necessary. We work with a wide variety of breeds, including English and French bulldogs, and will take every precaution to ensure that mother and pups are healthy. To learn more about our extensive safety protocols, please visit our veterinary surgery section.

Just wanted to let you know that Allie is doing great after Lap Spay on 4-10-12. Took her one day and she was back to normal. What a great way to get a dog spayed- I will recommend it to all my friends. Here is a photo of Allie that I took yesterday in our pasture with California Poppies. I thought it was cute! Thanks again!!

I have been taking my Beagle, Destiny, to Sylvan Vet for the last 10 years. She has had many medical problems throughout her life. There were times that I didn’t think she was going to pull though, yet, with wonderful Veterinarians like Dr. Tiffany Cardoza and Dr. Kipp Magnussen, she is still here with me today. I am grateful for their expertise in knowing exactly what she needs and for their compassion towards the both of us, in our hour of need. We are very blessed to know that compassionate help is always there. My deepest thanks and appreciation.

Sylvan Veterinary Hospital has been an important part of our family’s life for several years now. Most recently they helped to preserve our pug Sweetie’s vision with a new surgery technique. Everyone in the hospital works diligently to serve our needs. There is open communication with the front office staff, the technicians and the doctors whenever necessary. Our concerns and questions are always addressed quickly and the doctors are always available to us whenever needed.

What a great neighborhood veterinary clinic! I love the convenient hours and boarding facility. They have a nice, friendly staff and team of doctors who involve me in making the right choice for my pet.

I can’t say enough about the miraculous results you can get from laser therapy. I used it for my puppy’s foot wound that wouldn’t hold stitches. The wound was completely closed in three treatments-without a scar! Also, this pup has elbow dysplasia and laser has helped him quickly regain soundness when he played too roughly. And the best part- it’s not expensive. I’m a tried-and-true believer of this technology.

Eleven years ago, Dr. Kipp Magnussen saved the life of my young kitten and I was genuinely impressed with his compassion and competence. Over the years I have been extremely happy with the care all the vets and vet techs have provided for my various dogs and cats. In addition, it is a mark of commitment to the highest standards of quality medical care that Sylvan Vet is accredited through the AAHA. I continue to highly recommend this clinic.

We have been a client of Sylvan Vet for the past 20 years. Just recently, Bodie, our Chocolate Lab experienced a wound to his back that was quite serious. After two months of patience, determination and constant care by Dr. Kipp Magnussen, Bodie has been nursed back to health. Kipp's staff has become family to us. Each and every one of them is kind, friendly and compassionate! Bodie just celebrated his tenth Birthday and is even swimming again. Thank you Sylvan Vet!!

I love the doctors and staff at Sylvan Veterinary Hospital for the care and compassion they have given my dogs over the years. From luxating patella surgery to nail cleaning, the care level is the highest. I would recommend them to any and all pet owners.
