Reproductive Health & Neutering
When to contact your vet
Use the level of concern to act; this guide cannot rule out disease.
Emergency: call immediately
Collapse, severe pain, marked weakness, repeated vomiting or a swollen painful abdomen needs immediate veterinary contact. Suspected pyometra is an emergency: contact the practice or out-of-hours service now. Do not wait for every sign or for discharge.
Prompt assessment: contact today
Seek advice today for heavy or unusual bleeding, foul-smelling or pus-like discharge, significant appetite or drinking changes, new abdominal swelling, pain or suspected infection. If the dog is unwell or worsening, escalate immediately. Explain when her last season occurred.
Routine advice
Arrange a routine discussion for cycle patterns, preparing for a first season and individual neutering decisions when she is otherwise well. Any uncertainty about illness should be discussed sooner; a checklist is not clearance to wait.
Pyometra can be hidden
Pyometra is a potentially life-threatening infection of the uterus, often in the weeks after a season. A closed cervix can mean there is no visible discharge. Thirst, vomiting, reduced appetite or tiredness can be warning signs; do not dismiss them as hormones.
Do not predict fertile days
A tracker cannot determine fertility, establish a safe mating date or replace veterinary assessment. Do not use bleeding, its cessation or calendar estimates to decide that mating is safe.
