I will take him to the vet if his weight still goes down but any suggestions on the cause would be appreciated.
I wouldn´t wait for him to lose more weight. If his teeth need filing he will bounce back slower with additional weight loss. Do make sure your vet knows what he´s doing. Do handfeed to keep up his strength and weight.
The Pig, The Vet & Teeth
This is the dental vet site and there is an Australian vet listed.
You will have to find out if he knows pig teeth and if he does and isn´t close to you, maybe your vet can consult.
I think I will take him to the vet for a checkup. I did wonder whether the weight loss was because Boots has become the dominant pig now he has grown up, and although he and Sneakers dont fight any more, Boots does like to chase him away from the food bowl when I put greens down (I have three pellet bowls and bottles so there is always one available). Lately I have been feeding Sneakers separately so that should keep his strength up.
Unfortunately, the dental vet on the website is in Sydney and I am in Adelaide (about 2000 miles away) but my vet is an exotics vet and has been great with other problems I have had.
Thanks again for your advice.
My vet has only done this a few times although he is an exotics vet and is the RSPCA vet. Here in Adelaide there is only one vet dentist and he doesn´t do guinea pigs.
My vet says that here in Australia there is just not the equipment available that vets in the US have, but he will do his best - he says it will depend on the extent of Sneakers´ problem. Keep your fingers crossed for him.
It can correct minor overgrowth.
