Is my dog pregnant?

In the days before high walls and fences in South Africa, it was quite common for dogs to roam around freely in cities and towns; and it was not uncommon to discover out of the blue, that your female dog at home may be pregnant without you knowing how she fell pregnant.

Having said that, in those days most people who had an un-spayed (unsterilized) bitch at home, would have known very well that she was “in season” or “on heat”, which is the time the female dog is ready to ovulate and mate, because the whole neighbourhoods’ male dogs would have been howling at the door for “a piece of the action”.

What is elbow dysplasia?

Elbow dysplasia is the collective term that describes a number of conditions that affect the growth and development of a dog’s elbow. It is most commonly seen in large and giant breed dogs. Labradors, Golden Retrievers, German Shepherds and Rottweilers are the most common breeds but it can occur in any breed. There are a number of different theories as to why elbow dysplasia occurs but it is often a combination of factors, which leads to the abnormal development of the joint. Defects in cartilage growth, trauma to the joint, genetics, exercise and diet may all play a role in the development and progression of elbow dysplasia.

Ear cropping in dogs was a procedure done by vets in the previous century whenever dog owners requested it. Cropping is the removal of part, or all, of the outer ear, or the pinnae (externally visible flap) of the ear of an animal. Cropping the ears also involved taping the ears up after the surgery, to make the ears pointy.

Why was ear cropping done in the past?

Ear cropping was historically done on working dogs to reduce the risk of medical conditions like infections or haematoma. An othaematoma is when a small blood vessel in the ear bursts when dogs shake their heads (with ears flapping from side to side against the top and bottom of the dog’s head) and which causes the ear to “balloon” out with a blood-filled pocket in the ear. Although these initial reasons for doing cropping were sound, it turned into a cosmetic procedure over time and became more about “the looks” of the animal, rather than anything else. The surgical procedure of ear cropping was no longer done for functional reasons and was purely done for aesthetic reasons – “to give a dog that mean look”.

To start off with let’s define what we are talking about when we are talking about tail docking in dogs.

Tail docking from a veterinary perspective refers to a surgical procedure done to puppies between the ages of 3 to 5 days old, where a portion or partial length of the tail is amputated or cut off with a scalpel or surgical scissors, bleeding is stopped by cauterisation or tying off of bleeding blood vessels with absorbable suture material, and placing a suture or sutures in the skin to close off the wound.

Pyometra is a condition of unsterilised females, usually older than 6 years of age. “Pyo” refers to pus, and “metra” to the uterus. Literally translated, it would mean “bad of pus”. It is a very serious condition and if left untreated for too long, can have deadly consequences. It can be treated very effectively if caught early and taking your animal to the vet when signs first appear can save its life.

Pets are known to have an acute sense of hearing. What would cause them to lose this ability? How will they cope with deafness? To answer these questions we first have to look at the normal anatomy of the ear.

Dog and cats ears, much like humans, can be divided into three areas: the outer ear, middle ear and inner ear.

• The outer ear consists of the external earflap called the pinna, and the ear canal which is a narrow tube through which sound vibrations enter the ear.
• The middle ear contains the eardrum, a membrane that vibrates correspondingly to the incoming sound waves, and the small little bones on the inside of the eardrum called the auditory ossicles. These small bones transmit the eardrum vibrations to the inner ear.
• The inner ear, located deeper within the skull, contains the cochlea, a snail-shaped structure containing nerve endings that receive the vibrations and pass nervous system signals along to the brain, thereby enabling hearing.

False pregnancy, also known as Phantom pregnancy or Pseudo-pregnancy, is a condition of both dogs and cats, whereby the unsterilised female animal (regardless of whether she was mated or not) shows some or all of the typical signs of pregnancy but is not really pregnant. In other words, she shows mammary gland development (with or without milk production) but does not produce any offspring.

Understanding the female’s cycle

A female dog will only come into heat for the first time between the age of seven months and anytime up to a year of age. Occasionally this period may be longer. The age at which they first come into heat is governed by a combination of factors but usually smaller breeds start at a slightly younger age than the larger breeds. This is by no means a set rule as there is a great variation. Once she has started to cycle, a female dog will then come into heat every 4 to 7 months but your giant breed dogs may only cycle once every 12 to 18 months. It can take up to 2 years for them to develop regular cycles. Once started the heat cycle can last 2 to 3 weeks. There are two main parts to a female’s cycles namely pro-oestrous and oestrous. Pro-oestrous is the period during which her vulva will be very swollen, she may have a bloody discharge (volume varies greatly) and she will not allow any males to mount her. This is essentially the non-receptive part of her cycle. The second part is known as oestrous. At this point her vulva is still swollen, any bleeding has stopped and most importantly this is the period during which she is receptive to males and will allow mating. It is essential to understand this to avoid unwanted pregnancy. It is only when the bleeding stops that she is in full heat and at her most fertile.

Cryptorchidism is a condition where the male dog or cat’s testicles have not descended into the scrotum. Descended in this context means that the testicles has come from inside the dog or cat’s belly and are visibly sitting in the ball sack (scrotum).

In the embryo, when the kitten or puppy is being formed in the mother’s womb, the testicles develop inside the puppy or kitten’s abdomen (stomach cavity) behind the kidneys. As the embryo matures, the testicles then move from the inside to the outside of the animal’s abdomen.

Having a new puppy join your family can be one of the most exhilarating experiences for a family but if not done the right way it can have disastrous consequences. People often let emotions get the better of them and don’t make informed decisions. A new puppy will become part of the family for the rest of its life and you will be responsible for its wellbeing. Before getting a new puppy, there are a number of things one has to consider.
