Hi Misty,
Perhaps it might help if your daughter & her partner figure out some compromises before they try to determine any specific breed. The following considered:
Size of Dog
Personality --- what do they want: independent, needy, loving, working, companion, Instant obedience or just kind of in the ballfield type?
* Coat length --- Long - med- short
Hair or Fur? One needs regular trimming, the other sheds and can have more than a single coat.
* Activity level: How much exercise and participation are they really wanting to do?
--- Small [$ Giant breeds "Tend" to need less exercise than Med & Large breeds. (notice everyone, I said "tend" ]-) )
Some breeds are workers and need more than the average: for instance: Jack Russells are busy dogs and NEED to be busy, so are Border Collies. Sighthounds have reputations for being couch potatos, despite their size :D :D Labs, GSDs, & Rotties, do need more exercise and activity than other breeds. I'm just skimming. Obviously, she has to do some research on breed profiles. But this is one of those make/break categories. If they have a dog that is not getting the attention and activity it needs, that's where a lot of destruction begins to happen.
If they both work and are gone all day, perhaps they might consider looking into adopting a 10 month old and older dog. Personality and habits are easier to determine, plus it's much easier adapting a "mostly-grown" dog to a household, than a six week old puppy.
I hope this gives them some ideas on where to begin. Worse comes to worse, there are online questionaires that help to determine what type of dog is best suited to a household. Just do a search on Google. Just remember, they do tend to be limited on what breeds would fit (usually AKC), but it gives an idea on where to look and expand a search.
good luck,
toodles
