Preparing Pomeranians for breeding involves three questions: are both dogs fit to reproduce, would pregnancy be acceptable for the female, and which risks might affect their puppies?

Start with overall health and body condition
The veterinarian reviews illness history, body condition, breathing, heart, movement, skin, teeth and medication. Assessments depend on age, symptoms and breed considerations. Routine examination cannot exclude every hidden problem but identifies where further investigation may help.
Mention coughing after exercise, fainting, lameness, heat intolerance or appetite changes even if your Pomeranian appears well between episodes. Specific observations are more useful than saying the dog has always been active. Recent illness also matters; the arrival of a heat does not oblige you to use that cycle.
The female needs a reproductive assessment
Prebreeding assessment includes the mammary glands and reproductive passage. A veterinarian may identify narrowing or another anatomical feature affecting mating or delivery. The clinician selects a suitable examination; owners should never attempt to check vaginal patency themselves.
Previous difficult births, pregnancy losses, unusual discharge, pain during mating and reproductive surgery matter. Normal heat cannot answer those questions. For each investigation, establish which problem it should confirm or exclude and how the finding would change the breeding decision.

Assess the male's mating ability and fertility separately
The male examination includes external genitalia and testes; a complete reproductive evaluation also assesses semen. Sexual excitement does not establish semen quality, and previously sired puppies do not guarantee unchanged fertility today.
Separate two questions: can the dog mate comfortably, and does the ejaculate contain suitable sperm? A keen male can have a problem with the second, while another may produce sperm but struggle physically with mating. An absence of reported symptoms therefore cannot replace assessment, especially after unsuccessful breedings or illness.

Which checks are relevant to Pomeranians?
American Pomeranian Club guidance includes patellar, heart and eye screening. This is a useful breed reference, not a universal legal breeding licence. For a German Kleinspitz, confirm the programme appropriate to that variety and the local breeding system.
Knee, eye and heart assessments answer different questions. “Health tested” is too vague: identify the method, dog's age and result. Discuss what any finding means for the dog's wellbeing and mate selection, rather than considering only whether a certificate can be issued.
DNA tests cannot replace clinical screening
A genetic test looks for a particular variant, whereas clinical screening evaluates signs of disease or the organ itself. Eye screening, for example, involves a veterinary ophthalmologist. Several negative DNA reports do not rule out every inherited condition.
Check whether the selected test is validated for the breed and whether parental combinations have a clear interpretation. A large panel may contain relatively few useful results for your particular pair. Certificate numbers alone are not a measure of breeding quality; relevant investigations and transparent findings matter more than the length of a list.
Match tests and preventive care to their purpose
Blood counts, biochemistry, urinalysis, imaging or specialist consultations depend on history and examination findings rather than one identical package for every dog. Vaccination planning considers previous vaccination, infection exposure and local requirements, and should be discussed ahead of breeding.
Ask what a proposed result would change. Infection screening, organ assessment and ovulation timing serve different purposes. Disclose every medicine and supplement: a familiar product is not automatically suitable throughout reproduction. Do not discontinue treatment for chronic illness or add preventive medication without veterinary advice.

Preparation can change the breeding decision
When disease is identified, clarify its diagnosis, prognosis and implications for pregnancy or use of the male. Reproductive specialists can work with imaging, surgical and other services. Postponing breeding is a valid outcome when assessment shows that the original plan is unsuitable.
A useful conclusion states what has been assessed, which limitations remain and what must change before reconsideration. “Appears healthy” cannot guarantee healthy puppies. Choose the pair using verified findings for both animals.
