Pack the routine, not just the dog
A weekend stay works when your dog arrives to find her own life already there. Send the exact food she eats at home, measured into portions for each meal so there is no scooping guesswork and no well-meant substitution with whatever is in the other cupboard, which is a common cause of a Monday upset stomach. Include her own bedding or at least the blanket from her home bed, because scent is the fastest settler a dog has, plus a worn item of your clothing for the first night if she is a dog who checks where you have gone. Add a short note — feed times, how her food is served, her last walk and toilet time before bed, any quirks such as needing the garden door open a crack at dawn — and keep that note updated as she changes.
Agree the sleep setup in the other home honestly
Where she sleeps at your co-parent's home matters more than where she sleeps at yours, because it is the arrangement she has to relearn each Friday. Best is a direct copy: same type of bed, placed in the same sort of spot, ideally a quiet corner of a bedroom if that is her home pattern, with the same settle-down sequence of last toilet trip, water check and lights out. If the other home cannot allow dogs in bedrooms, agree the alternative once and keep it constant, rather than letting her sleep in the kitchen one weekend and a child's room the next. Expect some restlessness on the first night of each stay early on; a familiar chew, a calm brief reassurance and then boring consistency settle it faster than taking her into bed as an exception that cannot be repeated.
Keep feeding discipline identical in both kitchens
Weekend homes drift toward treats: extra biscuits for a visiting dog, leftovers in her bowl, a later breakfast because the house sleeps in. Each small kindness moves her stomach, her weight and her Monday expectations. Agree that she is fed at near enough her home times, that treats come from the supply you send, and that human food stays out of her bowl entirely. Keep fresh water in the same place in the kitchen so she is not hunting for it, and ask for a quick note of anything she refused, stole or was sick after, because that information belongs to her whole week, not just the weekend. If she regularly comes home with an upset stomach, off her food or wired and overtired, treat it as a routine problem to fix together, not a criticism of the other home.
Make Monday the test of whether it is working
A settled weekend dog comes home, greets you, and slots back into her weekday pattern by the evening. A dog who is frantic, exhausted, off her food or toileting indoors on Mondays is telling you the two patterns are too far apart. Compare notes factually with your co-parent — sleep, food, walks, anything new — and close the biggest gap first, whether that is bedtime, breakfast time or how much exciting visitor activity she gets. If appetite loss, repeated stomach upsets or anxiety around packing and travel persist despite matched routines, discuss it with your vet. KinsLe Care Pass hands your co-parent her current feeding amounts, sleep setup and bedtime routine for each stay and then ends, so the weekend home always works from her latest details rather than last month's note on the fridge.
