Guinea Pig Breeding


Before any decision is made to breed from your pet, regardless of species, remeber that there are many pet's in resuce homes that are in need of rehoming.   You must ensure you have a plan for the off-spring and the responsibility you have to them as the owner, if you are unable to find suitable homes.   Guinea Pigs can have large litters of up to 7, a lot of Guinea Pigs that will need a loving forever home.   If you do not plan to keep all of the off-spring find out if there is a market for them - and by that we mean friends and family.   Baby animals are very cute, but they will grow.   Guinea Pigs reach sexual maturity at a VERY early age.  But if you have ticked all the boxes and are ready to breed from your Guinea Pig, the following advice will help you ...
It is advisable to bring your Guinea Pigs to us for a full check up, before breeding commences. They need to be in good health to produce healthy offspring. Overweight and underweight Guinea Pigs should not be bred from. 

Male Guinea Pigs become sexually active around 8-10 weeks old and females between 4-5 weeks. 

The female is pregnant for 65-72 days and the offspring are fully formed, eyes open and eating solid food within 24 hours, as well as feeding from their mum. 

Guinea Pigs can become pregnant as early as 12 weeks and alarmingly can become pregnant up to five times a year, even straight after giving birth! 

Guinea Pigs need to have their first litter before they are a year old. This is before their pelvis fuses, narrowing the birth canal. If their first litter is after this time they will have difficulty in giving birth and should not be bred from. 

Male Guinea Pigs can be castrated and for most pet owners wanting to keep male and female Guinea Pigs together this is the best advice. 

Guinea Pigs have a life expectancy of 4-7 years.
