Micro-chipping is now the most common internationally recognized means of identifying companion animals.
1) What is a microchip?
Microchip is a Radio Frequency Identification Device (RFID). It is actually a basic computer complete with a radio receiver and transmitter with aerial attached.
2) How many types of identification numbers and microchips are there? Different manufacturers in the past produce different type of microchips and thus different identification system. Currently, efforts are put in place to ensure compatibility and consistent distinctive identification numbers produced between these different manufacturers worldwide. We currently use International Standards Organisation (ISO), technically referred to as FDX-B in Singapore and most parts of the world.
3) Are all microchips the same?
Microchips are encapsulated in glass. Some have these glass capsules coated or attached to plastic caps to prevent migration; others, may not have.
4) After implantation, is there a need to plaster the point of entry (of the needle) to prevent bacteria infection and microchip from falling out?
The skin of dogs, cats, rabbits and G. pigs are more elastic compared to that of humans. If microchipped properly (with sterilised microchip gun and microchip), the vet will be able to gently massage the area of insertion to ensure the elasticity of the skin seals the entry site. However, if in doubt, a little tissue glue over the wound can be helpful. Generally, tissue glue is imperative in reptiles.
If done properly, and with sterilised equipments, the chance of infection is low.
5) Is it advisable to anaesthetize my pet dog for microchipping?
When anaesthetized, there is a tendency for the microchip to be implanted too laterally if the animal is in lateral recumbency (that is lying on its side during anesthesia). As such, it is important that the animal is in a relatively normal lying position to ensure the microchip is implanted in the midline (dorsal to the scapula- that is slightly forwards just infront of the shoulder blade). If an animal is not too stressed or not aggressive during microchipping, no general anesthesia is required. You may however enquire about localized pain killer to the site of injection, if you are concerned.
6) How is the microchip read?
It is read by a compatible microchip reader. The reader emits a radio signal that energises the microchip. Once energized, it responds by transmitting a signal back to the reader. An ISO microchip will respond by transmitting back a 15 digit number embedded in the microchip, displaying the number on the screen of the microchip reader.
7) Problems with microchips. Does it cause bad skin problem at where the microchip is?
Generally extremely safe. There have been isolated reports of microchip glass bursting; and, the rare inflammatory respond at the site.
Ear Infection in Your Pets.
Ear infection (Otitis) is common.
Ear infection (Otitis) is common in both dogs and cats. Some signs of otits include ears-scratching, head-tilting, inability to open jaw fully and smelly ears with discharge.
Otitis is usually caused by overgrown of bacteria. In Singapore, yeast and mite infection are very common. The ear canal in your pet is an inverted "L". When an infection occurs, the shap/anatomy of the ear canal acts as an incubator for organism to grow.
It is importnat to use an otoscope to check that the ear drums are intact. Many ear cleaners such as those which contain propylene glycol and carbamide peroxide have been reported to be ototoxic when the ear drums are not intact. I advise against using products containing them if you are uncertain whether the ear drums are intact! I will also do ear smears and look under the microscope to find the causative organism of the ear infection.
Checking the type of organism which triggers the ear problem is important. For example, there are many different type of bacteria, and by looking under the microscope, the basic group of bacteria that is causing the problem can be pin-pointed. This will then allow presciption of appropriate medications to treat the ear problem. Inappropriate antibiotic usage may cause bacteria resistance and may possibly create superbig infects.
Otitis is a common condition which generally can be cured, painlessly and quickly, with early diagnosis and treatment.
