Jack Russell Terrier health guide
Also known as: JRT, Parson Russell Terrier
About this breed
Jack Russells are small dogs with working-terrier engines that commonly run happily into their late teens. Knees, eyes and kneecap-adjacent hip disease in youth are the main issues, plus the injuries their fearless temperament invites.
Living in Macau's climate
This busy terrier keeps sprinting in heat, so enforce shaded rest and water on humid summer days. The short coat needs little grooming but weekly checks for ticks after grassy or hillside walks around Macau are wise.
Common health conditions
Patellar luxation
Signs: Hind-leg skipping during fast turns and play.
Prevention: Lean weight and yearly knee grading; surgery fixes persistent cases well.
Primary lens luxation
Signs: A suddenly painful, red, cloudy eye, usually between 3 and 8 years.
Prevention: A DNA test identifies at-risk dogs; treat any sudden eye pain as an emergency.
Legg-Calve-Perthes disease
Signs: Progressive hind-leg lameness in dogs under 18 months.
Prevention: Early X-rays for persistent puppy limps; surgical treatment works very well.
Dental disease
Signs: Tartar and gum disease hidden behind an active lifestyle.
Prevention: Daily brushing and dental checks at annual visits.
Daily care tips
- Channel the energy: two proper exercise sessions plus games daily.
- Check for ticks after hill and grass walks every week.
- Treat sudden eye redness or pain as a same-day emergency.
- Ask about the lens luxation DNA test in the first year.
