American Water Spaniel Considerations
Unlike many spaniels that greet everyone as a friend, the AWS is naturally reserved and can be suspicious of strangers. Without extensive early socialization (between 8–16 weeks), this trait can escalate into fear-based reactivity or excessive territorial barking. They are watchdogs first, greeters second.
This breed is prone to becoming a "Velcro dog." They bond intensely with their primary handler and often struggle when left alone. This can manifest as destructive chewing, pacing, or frantic vocalization (whining/howling) if isolation training is not prioritized early.
The AWS has a tenacious working heritage. This drive can sometimes translate into possessiveness over food, toys, or high-value chews. It is a manageable trait but requires an owner who understands trade-up protocols rather than forceful removal.
While eager to please in the field, they can be manipulative and independent in the home. They are not blindly obedient; they often ask "What's in it for me?" before complying.
Boston Terrier Considerations
Boston Terriers are extreme 'Velcro dogs' that bond intensely. Left alone for more than 4-6 hours, they develop destructive chewing, house soiling, and persistent vocalization. Not suitable if all adults work full-time away from home.
It is impossible to overstate this issue. Their brachycephalic anatomy causes them to swallow air while eating, resulting in frequent, potent gas. If flatulence repulses you rather than amuses you, this is NOT your breed.
Their shortened airways prevent efficient panting. They are at HIGH RISK of heatstroke at temperatures above 25°C (77°F). Air conditioning is a requirement, not a luxury. You cannot take them jogging or hiking in summer.
Expect loud snoring, snorting, and episodes of reverse sneezing that sound like the dog is choking. If you need silence to sleep, this breed is not for you.

Boston Terrier Quirks
The Gas Factory
Expect frequent, potent flatulence due to swallowing air while eating. Slow-feeders and probiotics help reduce but never eliminate.
Reverse Sneezing
A spasm of the soft palate that sounds like a terrifying asthma attack. Usually harmless - gently massage throat to stop it.
The Sunbather
They LOVE to bake in sun patches, but must be supervised to prevent heatstroke. Their heat regulation is poor.
The Burrower
They love to sleep under blankets and will burrow into bedding. Perfect for cold nights, concerning for hot ones.
