WATFX has had some poor days.This sounds more like performance chasing than a fundamental reason to change horses. It has lost
1% in the past three months. About
1/2% worse than DODIX, and still in the middle quintile (barely, at 59th percentile) of its peers.
Rather than jumping at particular funds, I suggest thinking first about the type of fund you want to own. WATFX is an excellent vanilla bond fund; if that's the type of fund you want, I wouldn't switch. DODIX (and I'll add BCOIX) are great core plus funds. That means that they add a fair amount of junk bonds, which have higher yields but also tend to move more like stocks. PIMIX is a multisector fund. These funds tend to have even more junk and may dabble in international bonds.
PIMCO funds, virtually all of them, are off in their own world and it's difficult to say exactly what they're doing at any given instant. M* likes PIMIX, describing the fund as one that "stands out for historically large positions in nonagency mortgages, which have helped drive strong performance in a variety of different market environments. It also buys corporate debt, and emerging-markets and developed foreign sovereign debt, with a sprinkling of non-U.S. dollar currency bets."

You'd be switching from a vanilla, high credit quality bond fund, albeit a relatively racy one (above average risk), assuming any vanilla bond fund can be called racy.
Here are a couple of graphs that may help to illustrate what I mean about performance chasing and risks:
Performance since 8/10/20 (WATFX's peak for the year, I believe)
Notice that the core fund (WATFX), core plus funds (DODIX, BCOIX), and market average (US Aggregate index) tend to track together. So does the multisector fund PDIIX, though with wider swings both up and down. But PIMIX goes its own way.
Now zoom out to YTD (click on the YTD link in the graph). You'll see that both the PIMCO funds take on a lot more risk - a huge dip in March, relative to the other funds. Over the long term, risk usually pays off. But that line of reasoning also suggests paying less attention to short term movements.
Here's a second graph, same funds, this one for the three year period before 2020 (20
17-20
19). It shows both PIMCO multisector funds outperforming. Notice that aside from separating a bit, all the funds still tend to track together
except PIMIX. It diverges in the summer of 20
19, with performance dropping from that of PDIIX to that of the more conservative funds.
My suggestion is to think first about what kind of fund you want to own. You might still wind up investing in PIMIX, but it will be for reasons beyond its performance over the past couple of months.
