Health Concerns

Common health issues

While Rex Guinea Pigs are generally hardy pets, they can still be susceptible to certain health problems.

Respiratory infections

Guinea pigs are prone to respiratory infections, which can be caused by bacteria, viruses, or fungi. Signs of a respiratory infection include sneezing, coughing, nasal discharge, and difficulty breathing. If you suspect your guinea pig has a respiratory infection, consult a veterinarian immediately.

Vitamin C deficiency

Guinea pigs, like humans, cannot produce their own vitamin C and must obtain it through their diet. A deficiency in vitamin C can lead to scurvy, which is characterized by lethargy, weight loss, and swollen joints. Ensure your guinea pig receives adequate vitamin C through a balanced diet and vitamin supplements, if necessary.

Dental problems

Guinea pigs’ teeth grow continuously throughout their lives, and dental issues can arise if their teeth become overgrown or misaligned. Provide your guinea pig with plenty of hay and chew toys to help wear down their teeth, and monitor their dental health regularly.

Preventive care

Regular veterinary check-ups, proper diet, and good hygiene can help prevent many common health issues in Rex Guinea Pigs. Always consult your veterinarian if you notice any changes in your guinea pig’s behavior or appearance.
