‘Klondlike’ The Frozen Puppy!

 

‘Klondike’ Born From A Frozen Embryo

Beagle X Labrador Retriever puppy, “Klondike” now 9 months old is one of the first pups in the world to be born from a frozen embryo. He is a happy, healthy and very typical puppy, well developed and full of playful energy and the curiosity regarding just about everything, as puppies inclined to be!

Whilst his parents breeds are not endangered ones it is hoped that the technique used to produce Klondlike will also, in the future be used on and to preserve endangered and rare canine species, for example, the red wolf.

The technique in question is known as cryopreservation, a process that involves collecting and freezing, in this case scenario, fertilised eggs. Fertilisation occurs when as with Klondlike’s surrogate mum – a beagle, the female dog is able to become pregnant, and the embryo transferred to her. This is known as artificial insemination. Timing is vital as she will only “come on heat” once or twice yearly, so the window of time in which canine pregnancy can occur is very limited.

““Reproduction in dogs is remarkably different than in other mammals. We’re working to understand these differences so we can tackle issues ranging from developing contraceptives to preserving the genetic diversity of endangered animals through assisted reproduction.”   Alex Travis, who worked on the project and is director of Cornell’s campus-wide Centre for Wildlife Conservation.

The Pros and Cons of Neutering

 

To Neuter or Not to Neuter!

downloadSPAYING

PROS

  • Prevents bitch having puppies and false pregnancies
  • Normally eliminates inconvenience of seasons and stops the bleeding and behavioural changes.
  • Early spaying (before 1st season) drastically reduces the chances of mammary tumours later in life.
  • Completely removes the risk of Pyometra (uterine infection and a serious threat to all ages which can be fatal.
  • Helps with hierarchy problems but must spay lower ranking bitch only.

CONS

  • Temperament changes are possible with some bitches becoming more docile.
  • Small risk of urinary incontinence in early spaying but this can be treated easily.Neutering
  • Spaying, though routine, is major surgery. It is very uncommon but occasionally a haemorrhage can occur. There is also a small risk of problems within the skin wound.
  • The older the bitch is at the time of spaying (this should be around 9+ months) the greater the risks involved.
  • Recovery can take several days and it can take several weeks for her to heal. A follow up visit 7-10 days after spaying is necessary to remove the stitches.
  • Possible weight gain but if diet is properly adjusted and after spaying and appropriate exercise is given this should not be a problem.

CASTRATION

Neutering 2
NB CASTRATION IS NOT SUITABLE FOR ALL BEHAVIOUR PROBLEMS AND NEEDS TO BE CONSIDERED CAREFULLY.

PROS

  • Prevents the dog causing unwanted pregnancies
  • If done early prevents straying, leg lifting and territory marking
  • Prevents Testicular cancer (common cause of death in older dogs)
  • Reduces the risk of Prostrate cancer
  • Can cure hierarchy problems – between two males – so long as ONLY the LOWER ranking dog is neutered. This widens the gap between them and allows the higher ranking dog to take the top dog spot. NEVER neuter both – dogs are never equal.
  • Aggressive behaviour especially towards other dogs is usually reduced after castration.
  • Dominant/over amorous sexual behaviour is also normally much reduced. This results in less straying and helps to reduce traffic accidents.

  • Neutering is not a cure for all problems. It can help but also it could make no difference whatsoever:

E.G. It is unlikely to make any difference to: Wild and unruly behaviour or dog to dog/people aggression. And never to: Destructive behaviour and separation anxiety.

  • As with spayed bitches, castrated dogs can also experience changes in temperament, some becoming much quieter/docile.
  • As with spaying there is a possibility of weight gain after castration, but if diet is properly adjusted and controlled and appropriate exercise is given this should not be a problem.
  • Too late (around 12 months – peak of testosterone production) possible leading to a hormone driven “thug” dog for life.
  • Too young (around 7 months) risk dog will be thought of as female by other males due to not developing a proper masculine body and masculine behaviour. Vets do not usually castrate till around 9 months old.
  • Recovery usually takes 1-2 days with a follow up visit to remove stitches 7-10 days later.
NB Neither of these procedures are reversible! If there is any possibility of requirement to breed from a bitch at a later date or of having a dog at stud then neutering is not an option!
