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.

What is xylitol and where can it be found?

Xylitol is a natural sugar alcohol that is commonly used as a sugar substitute in human foods. It is found in and extracted from corn fiber, birch trees, hardwood trees as well as other fruits and vegetables.

Xylitol is a sugar substitute most commonly found in chewing gum, candies, breath mints, baked goods, cough syrup, children’s edible vitamins, mouth wash and tooth paste (all of the sugar free variety). There are many more human products on the market that may contain xylitol. It may also be purchased in a granulated form to be used for baking, or as a sweetener over cereals and in beverages. As society’s pressure to look lean and slim, and the need to diet increases, this sugar free alternative has grown drastically in popularity over the last decade.

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.

As a dog gets older, he or she may start to struggle to get up or get a little slower on walks. You may notice that they are worse in winter than in summer or after resting for a prolonged period. Sometimes they may not to be able to place any weight on a leg at all and this may happen quite suddenly. Lameness in older dogs can be broadly placed in three categories:

Getting home to find your puppy or young dog not placing weight on a leg is always a concern. There are many different reasons why a young dog may limp, some more serious than others. Causes of lameness can be broadly placed into three different categories:

• Lameness due to trauma
• Developmental and congenital (inherited) lameness
• Infectious causes of lameness and cancer

Because the causes of lameness can be so wide and varied, it is important to have your puppy looked at by the veterinarian sooner rather than later when you notice any signs of limping or lameness. 

Proptosis is defined, as the forward displacement of the globe (eyeball) out of the socket, with the eyelids trapped behind the globe.

Proptosis is an ophthalmic emergency. Any suspected trauma to your pet’s eye warrants a visit to your veterinarian immediately.

Let us first have a look at the normal eye anatomy:

Predisposing factors: Breed predisposition

Proptosis is a condition more commonly seen in Brachycephalic breeds (dogs with prominent bulging eyes, short noses and shallow eye sockets). Pekingese, Pug, Boston terrier and Shihtzu are over represented.

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.

Although most of us grew up with the assumption that bones are good for our pets this is in fact a fallacy, one that more pet owners should be made aware of.  Let’s look at some effects and risks involved when feeding bones to pets.

The Good:

The unfortunate truth is that the only good thing about feeding your dog bones is that they like it and it keeps them busy, especially if they have a tendency to chew. Sadly just as we all enjoy our McDonalds, KFC and pizza we know these foods are not good for our health and the same applies to bones for your dog. They carry no nutritional value and are indigestible. Perhaps the only part of the bone a dog may actually eat and digest would be bone marrow.

Feline acne is a common skin condition in cats. Cats of any age can be affected, and there is no breed or sex predisposition.

Cats are often presented to the veterinarian with the complaint of ‘dirt on the cat’s chin, that the owner cannot remove after attempts to clean it’ or ‘bumps on the cats chin’.

How does feline acne develop?

Hair follicles on the chin become blocked with secretions from small fat glands called sebaceous glands in the skin. This gives rise to multiple blackheads otherwise known as comedones on the chin, giving the chin the so-called ‘dirty appearance’. These comedones may also be associated with small red blisters or pimples and crusts on the surface of the chin.

The elusive and very unpleasant hairball is something that every cat owner will experience at some point. Cats in general are very clean and well-kept animals and grooming is an essential routine for them to ensure their cleanliness. A healthy cat is one that grooms.  Hairballs are simply a by-product of your cat’s hygiene.

A trichobezoar, commonly known as a hairball, is a clump of indigestible hair, moistened by bile and digestive fluid that may or may not contain bits of food or other foreign material. Hairballs are not usually round in shape but rather drawn-out and the shape of a sausage. This is due to their passage through the oesophagus, the tube connecting the stomach to the mouth, which is long and cylindrical. Hairballs can occasionally resemble faeces but on closer examination one will notice it is made up of hair. It also does not smell like faeces although it does not have a particularly pleasant odour.
