What is the proper Latin translation of this phrase: showdogs welcome?

I'm struggling to find the proper idea of a show dog. I'd also like to ensure that all grammar and punctuation are correct. Thank you!!What is the proper Latin translation of this phrase: showdogs welcome?
Perhaps, if you mean "welcome, showdogs" then:

salvete, canes ostendendi

salvete = welcome (second person plural present active imperative of salvo, I greet, welcome)
canes = dogs (nominative plural of canis, dog)
ostendendi = about to be exhibited (masculine nominative plural of ostendendus, future participle passive of ostendo, I show, exhibit, display)

If you mean "showdogs are welcome", then perhaps:

nobis grati sunt canes ostendendi

nobis = to us (dative of nos, we)
grati = welcome, acceptable (masculine nominative plural of gratus, welcome, acceptable, to agree with canes, dogs)
sunt = are (third person plural present indicative active of sum, I am)
canes = dogs (nominative plural of canis, dog)
ostendendi = about to be exhibited (masculine nominative plural of ostendendus, future participle passive of ostendo, I show, exhibit, display)

Done with a basic knowledge of Latin, not Google Translate.
