Ask what is known—and what is not
Ask about the dog’s age, previous home, veterinary history, current food and daily routine. Request the relevant records rather than relying on a verbal summary. A rescue may have limited history; an honest unknown is better than an assurance that cannot be supported.
Ask for observations
Ask what happens when the dog is left, meets unfamiliar dogs, has a collar or harness fitted, or is approached while resting. Find out where and how those observations were made. A brief meeting cannot establish that a dog will be comfortable with every child, animal or situation.
If you are considering a puppy
Ask to see the puppy with its mother in the place where it has been raised. Discuss the parents’ relevant health screening, early handling and social experiences. Check breed-specific tests with the appropriate breed club and your veterinarian; a general health check is not the same as screening for inherited conditions.
Agree on the next steps
Ask how introductions, settling in and follow-up support are handled. Clarify the adoption or purchase agreement, identification records and who you contact if difficulties arise. Avoid making a decision under time pressure. Share the information with everyone who will care for the dog.
