Storm and Sierra Litter – Week Two


“The Double Agent”

It’s been two weeks and Sierra hasn’t suspected a thing. We know that she gave birth to five puppies, but the count in her whelping box often fluctuates between five and seven. One of the regular visitors is Bailey’s Miss Saffron who does double duty in both boxes. This is helping to ensure that all puppies from both litters get equal access to the milk bar because it can get a little crowded there. Perhaps Sierra’s not very good at math, but it could also be that she’s just got a heart of Gold(en) and is happy to be their Godmother.

It’s exciting for us when the puppies’ eyes open. Puppies are born with their eyelids tightly shut because the eye itself is still developing and is extremely fragile. The closed eyelids serve as a barrier to protect the eyes from potential damage. Now that their eyes are open, it will take a few weeks before their eyes mature and their eyesight begins to approach normal. The puppies are also born functionally deaf since their ear canals are closed. While their ear canals begin to open at around the same time, the ears are much more fully formed than the eyes and their hearing will be quite acute within a week or so.

Many of the puppies’ critical organs including their brain are not fully formed and they will spend several weeks developing rapidly. Since the gestation period in dogs is short (63 days), the tradeoff is that puppies are quite helpless at birth. Biologists refer to species that produce immature dependent offspring as altricial, which means “to nurse, to rear or to nourish”. It refers to the need for the young of these species to be fed and taken care of for a long period of time. Within their first two weeks, these plump little princes and the princess crushed not only the 2 lb. barrier, but the 3 lb. barrier and are well on their way to the 4 lb. mark. We have a suspicion that someone’s been sneaking them Timbits, but of course they’re getting milk instead of coffee.

Despite their girth and zero stress lifestyle, the puppies are getting their share of exercise. Since we’ve added some stuffed animals to the whelping box, it forces the little ones to climb over the obstacles to reach their target (usually Sierra’s milk bar or a sibling to sleep on) thereby building muscle mass. As well, when they lie sleeping, they are constantly twitching – a state known as “activated sleep”. These involuntary actions help strengthen their leg muscles. This bunch will be on the dance floor before long.

That’s it for now, but be sure to join us next week for another riveting installment of “Puppy Tales”.

Ruly and Tulip Litter - Week 1

Ruly and Tulip Litter - 1 Week Old What a week it's been! The Tulip puppies continue to thrive, gaining weight steadily and remaining fairly quiet. Tulip dotes on her family, rarely straying far from the whelping box. As you can see on the 24/7 camera, she is starting to spend a bit more time outside the box, but she consistently checks on her babies. Tulip currently eats around 4 pounds of food per day, along with calcium and pre-probiotics supplements. As her pups grow, her daily food intake will be gradually increased, reaching 5 - 6 pounds per day by the time the pups are about 7 weeks old. This increased caloric intake is necessary to meet the energy demands of milk production and to maintain Tulip's own body condition. Tulip still believes an outdoor den would be best for her pups, so we are monitoring her closely when she ventures out. The whelping box is lined with padded bedding and clean, white bleached towels on the bottom. The white towels allow us to quickly spot a...

Ruly & Tulip Litter - Week 2

Many viewers of the 24/7 puppy camera have raised questions, such as what are the pipes running alongside the whelping box. These are called "pig rails" and they are designed to protect the puppies from their mother accidentally lying on them, ensuring the puppies' safety.  Since the puppies are unable to regulate their own body temperature, we use a heat lamp over the whelping box to keep them warm when Tulip is outside the box. However, we turn the heat lamp off when she is nursing the puppies. By 3 to 4 weeks of age, the puppies can regulate their temperature, which should then be in the normal range of 100.5°F to 102.5°F (38°C to 39.3°C). The most significant event this week is that the puppies' eyes have opened. Mr. Devil's eyes (the one with the red collar) were the first to open. Each puppy followed and within 48 hours they had all opened.  The puppies are now weighing almost 3 lbs, and Tulip provides them nourishment at least every 2 hours, often throughou...

Ruly and Tulip Litter - 7 Weeks Old

Tulip’s Puppies Celebrate Their 7-Week Milestone! Another week has flown by, and it's hard to believe these puppies are already 7 weeks old. For the most part, they've been a very quiet litter. Don't get me wrong, they have their moments of boundless energy, running around in circles like little tornadoes. But compared to some of my more "vocal" litters at this age, these pups have been relatively calm. They love attention and cuddles, which is a delight for us humans. The big adventure this week was the trip to the vet for their health checkups. I'm happy to report they received a clean bill of health and were a big hit at the clinic. However, I'm always on guard at the veterinary hospital, as that's where sick dogs go. So we quickly wheeled the crates into the exam room on a trolley, making sure to keep all other dogs and people clear of my pups. This time of year, the threats of kennel cough and parvo are ever-present. The puppies weren't sure a...
