as a generality:
they are VERY people orientated, they love their people, some bond very closly with one person other will bond with alot.
they are velcro dogs and do have a tendency towards seperation anxiety.
they are sighthoundish...they can be very aloof with strangers, and generally warey with strangers (even when well socilized)
they also tend to be sighthoundish in training methods, you will absolutly see them deciding wether or not its worth it to do as your asking...
they are active, ive met some "lazy" cresteds but for the most part the breed LOVES to run. and theres nothing more beautiful than seeing them open up and just run. my 2 will run for hours if youll let them. they will also walk for miles...
being small however they can get by with minimal outside excersize, they CAN get enough excersize running round in the house/garden, but a little extra goes along way.
they are clowns...jasper does things constantly that just make me laugh, he likes to lick the fishtank and chase the fish, or he'll talk to you, he likes ot sing along too...
if im sat on my laptop and he wants to snuggle he will shove his head under my arm untill i lift it then drape himself across the keyboard so ill snuggle him. Ruby is less in your face about it usually but when she REALY wants attention she will absolulty come over and bop you with her paw then roll over for belly rubs.
they dont love, they NEED attention, this is not a breed you want to get into if you dont enjoy spending all your time with them, i take a shower they like to pop their heads round the curtain every so often to make sure im still in there, leave the room they both get antsy ect...
as i type jasper is sat on my shoulder...this is a constant with them, they adroe their people and nothing in life is complete if there not with you...
this is NOT a breed to get if you dont like to groom.
hairless require weekly bathing, skin care, they get black heads and to keep them looking good most have some degree of body hair that is usually shaved off...
they require sunscreen in the summer as they WILL burn, and require clothing in the winter, its not a case of "pretty clothes" its a case of if you dont they WILL get cold.
i know cresties in florida that still need clothing in the winter, hairless adapt to thier "normal" and jasper is comfortable nekkid in the summer here in ct...but in the fall he will bring his jammies to me.
the powderpuff requires daily combing, regular (eveyr 2 weeks) bathing with conditioner...they dont get the black heads like the hiarless but they needs just as much attention, light powderpuffs will still burn in the sun and their hair isnt as insulating as many breeds so even though theyve got what looks like a big fluffy thick coat they often still need a little extra layering in the winter.
puff hair MATS like crazy.
many puff owners do a pony or puppycut on thier puffs too which while its easier on the combing, they need shaving frequently as their coat grows pretty quick.
they tend to be prone to food alergies, particularly corn and beats, they are also usually alergic to lanolin (found in sheep wool)
their nails grow fast.
the hairless is also prone to loosing their teeth, they are a "primitive" breed with a primitive mouth meaning the teeth shallow root (and are usually perminently sharper and more tusk like than most dogs teeth, most hairless teeth perminently have a "sharpend" "pointy" or "puppy" look...
watch for eye and knee issues, but otherwise there a pretty good healthed breed...
BUT...if you think you want a hairless, look at pictures of them when there older, they get wrinkles, liverspots, loose their teeth ect...if you dont love them when they look older, dont get one as most go that way lol.
also remember the dogs on things like the ugly dog contest are usually badly bred or rescue/abuse cases so there not all nessicarily gonna look that bad...
my dad still calls them gremlins.
also a warning...
they are addictive!
