To choose a veterinary clinic in Coronel Oviedo, start by separating the case: vaccinating a dog is not the same as treating a calf or a sow out in a rural compañía. For pets, look for a clinic near home with an emergency line; for farm animals, a vet who makes farm visits. Either way, call or message first to confirm they treat that species and can see you that day.
Pet or farm animal?
Oviedo is a city, but it is surrounded by farmland: the municipality includes 26 rural compañías, pig farming is a significant activity and about 35% of the land is pasture suited to cattle (Wikipedia (opens in a new tab)). So ask up front:
- Dogs and cats: appointment or walk-in? Do they do lab work, ultrasound or surgery on site, or refer you?
- Cattle, pigs or horses: do they come out to the farm, how far, and what does the trip cost?
- Emergencies: is there a night service or a number for weekends and holidays?
Save two numbers: your regular clinic and a backup in case the first can't see you.
How to tell if a clinic is licensed
Senacsa, the national animal health service, licenses veterinary clinics. It requires a veterinary technical adviser with professional registration, a registered business and a commercial licence (patente comercial) (ABC Color (opens in a new tab)). Each vet must also register their degree with Senacsa and renew every year, with 31 March as the deadline without a surcharge (Ferrere (opens in a new tab)).
It's fine to ask who the responsible vet is. Complaints about malpractice or cruelty go to Senacsa's Animal Health and Welfare Directorate or to the public prosecutor.
When to vaccinate against rabies
For dogs and cats the schedule starts from three months of age, with boosters at 30 days and at six months, then one dose a year for life (ABC Color (opens in a new tab)). Always bring the vaccination booklet so the dose is recorded.
Keep cattle? Watch for bovine rabies
In April 2026 there were bovine rabies outbreaks in several departments, including Guairá, San Pedro, Canindeyú and Cordillera. Senacsa began vaccinating in the affected area, is distributing free doses to every department and asks farmers to report cases (La Nación (opens in a new tab)). If you suspect rabies in an animal, don't handle it unprotected; call your vet and notify Senacsa. Ask your vet when to vaccinate the herd if doses reach your area.
Heat and leishmaniasis: when to see a vet
Summer highs in Oviedo reach 42 °C (Wikipedia (opens in a new tab)). On those days, walk dogs early or at night, leave water and shade, and get help fast if a dog pants nonstop or collapses.
Canine leishmaniasis is another reason to book a visit. Signs include gradual weight loss, skin lesions with hair loss or ulcers, overgrown nails, swollen lymph nodes, nosebleeds and eye problems. The Centro Antirrábico Nacional on the UNA campus in San Lorenzo tests dogs from 6 months old for free, Monday to Friday 7:00–22:00 and weekends and holidays 7:00–19:00 (La Nación (opens in a new tab)).
Referred to Asunción?
Oviedo is 132 km from Asunción on Route PY02. For tests or surgery not available locally, one referral option is the veterinary hospital of UNA's Faculty of Veterinary Sciences at Ruta Mcal. Estigarribia km 11.5, San Lorenzo; the hospital area is open 6:00–20:00 (FCV-UNA (opens in a new tab)). Before you drive:
- Ask your vet for a written case summary and any test results.
- Call ahead to confirm they can take you that day.
- Bring water and a lead or carrier, and travel outside the midday heat.
